GENERAL DESCRIPTION The TDA5147CH is an ASIC combination chip that includes the following functions: spindle motor driver voice coil motor driver retract Power-on. The circuit is contained in a 64-pin QFP package. The TDA5147CH is controlled by a custom digital ASIC (see Chapter "Application Information"). The custom ASIC provides the necessary commutation sequences for the spindle drivers via the SCNTL1, SCNTL2 and SCNTL3 inputs. Spindle speed is monitored by comparator outputs SENU, SENV and SENWIS. Motor speed control is accomplished by a PWM signal (input at pin SIPWM). Control of the VCM circuits is via the VIPWMH and VIPWML input signals. These inputs provide control of the voice coil current.

MGG842 Fig.3 Pin configuration. 1997 Jul 09 7 Philips Semiconductors Preliminary specification 12 V Voice Coil Motor (VCM) driver and spindle motor drive combination chip FUNCTIONAL DESCRIPTION Spindle drivers The spindle section (see Fig.2) contains both the low and high side drivers (configured as H bridges) for a three-phase DC brushless motor. Back EMF (Electro Motive Force) sensing of the commutation rate (pin SENWIS) is an output to an external digital ASIC circuit. This circuit should provide the input commutation control as well. Consequently, all speed control, start-up routine and commutation control will be generated by the external digital circuit. The SIPWM signal from the digital circuit is used to control the spindle current. This PWM signal is internally filtered. The output of this filter depends solely on the duty factor. The pole location of this first order low-pass filter is controlled by an external capacitor at pin SPWMFLT. Dynamic braking is possible only during non power-down situations and must be initiated by the digital circuit. A 3- level mode line (pin SMODE1) allows for: * Induction sensing in pre-start-up (SMODE1 = 0.5VCC5 or high impedance) * PWM control during start-up (SMODE1 = 0 V) * Linear control (SMODE1 = VCC5). SENSING MODE The induction sensing mode can be used to sense the rotor position and to spin-up with high current. To sense the rotor position, one of the BEMF sensor outputs (pin SENWIS) will be shared with the voltage comparator that is used for the induction sensing function. Prior to start-up each phase is excited for a short period of time. The current from each coil can be monitored via the multiplexed output (SENWIS). By comparing the rise times of each phase the rotor position can be determined. In cases where the spindle motor requires more current to spin-up, the sensing mode is used with the exception that the output SENWIS is ignored. The output drivers are operated in saturation in the sensing mode, so the motor current is only limited by the power supply. This condition of induction sense mode can be used to overcome the head friction and must only be used when needed. PWM MODE The PWM mode is normally used during the start-up phase. Maximum drive voltage is applied to the low drivers to obtain high start-up torque. The purpose of the PWM TDA5147CH mode is to drive the low drivers into saturation, because saturation reduces the power dissipation during start-up. When the spindle current reaches the value destined by the duty factor of the signal at pin SIPWM, a one-shot is fired. The output of the one-shot remains HIGH for the programmed off-time (toff) set by the RC-network at pin SPWMTC. The one-shot is not retriggerable for approximately 10% of the off-time, giving a minimum for the on-time of 0.1toff. During the off-time, the lower spindle output drivers are switched off. The on-time of the drivers is determined by the charging time of the coil current. The turn-off time follows: toff = R x C ln(2) With R = 68 k and C = 220 pF, toff = 10.4 s CV The minimum on-time is: t on = -------I LINEAR MODE The linear mode is used when the motor is near to its intended speed. It can also be used at start-up, but higher power dissipation will occur. In the linear mode the drivers are controlled by a sensing amplifier. A Miller network is used to obtain soft switching on the lower drivers. This prevents large voltage spikes on the motor coils when the lower drivers are switching. The high drivers are switched into the linear (resistive) region. The transconductance gain of the low driver current to filter voltage can be calculated as follows: I coil 11 1 V SISENH G m = --------------------------- = ------ --------------------------- = ------ = -- = A/V V SPWMFLT R s V SPWMFLT R s 5 For a 100% duty factor at SIPWM, the nominal voltage at SPWMFLT = 1.74 V. The calculated coil current for a 100% duty factor (sense resistors Rs = 0.33 ) is: 1 1 I coil = ---------- x -- x 1.74 = 1.05 A -0.33 5 Referencing to the duty factor, the coil current is: 0% duty 11 0% duty 1 I coil = ------ = -- x 1.74 x -------------------- = ------ ( 0.348 ) x -------------------100 Rs 5 100 Rs The duty factor is arranged so that at 100%, the voltage SPWMFLT = 1.74 V and at a 5% duty factor SPWMFLT = 0 V. This is to ensure that at 0% duty factor the current will be zero (allowances for circuit tolerances). The input decoder is driven by three lines which define the windings to be energized. The input decoder must then translate these lines to six lines to drive the six output drivers. The truth table is given in Table 1. The status of each block in the spindle drive section during the possible modes of operation is given in Table 4 8 1997 Jul 09 Philips Semiconductors Preliminary specification 12 V Voice Coil Motor (VCM) driver and spindle motor drive combination chip Table 1 Input decoder truth table for spindle motor drivers CONDITION Disable Dynamic brake State 1 State 2 State 3 State 4 State 5 State 6 Under voltage Note 1. x = high impedance. VCM driver The VCM driver (see Fig.1) is a linear, class AB, H-bridge type power driver with all power devices internal to the IC. In addition to the power stage a sense resistor enables the VCM current to be measured. The VCM current is controlled (see Fig.5) via two PWM signals, VIPWMH and VIPWML, that are generated by the digital circuit. The signal at pin VIPWMH weights 32 times more than the signal at pin VIPWML, thus the current is proportional to the duty factor of (VIPWML + 32 x VIPWMH). These PWM signals are filtered by using an internal 3rd-order low-pass filter (Butterworth filter).The bandwidth of this low-pass filter is Table 2 VPCNTL and SCNTL modes VPCNTL INPUT STATE(1) VCC5 0.5VCC5 or high impedance 0V X X X 0.5VCC5 or high impedance SCNTL1 LOW HIGH HIGH HIGH HIGH LOW LOW LOW - SCNTL2 LOW HIGH HIGH LOW LOW LOW HIGH HIGH - SCNTL3 LOW HIGH LOW LOW HIGH HIGH HIGH LOW - SDRVU(1) x HIGH LOW x HIGH HIGH x LOW x TDA5147CH SDRVV(1) x HIGH x LOW LOW x HIGH HIGH x SDRVW(1) x HIGH HIGH HIGH x LOW LOW x x nominally 40 kHz (less than 2 degrees lag at 500 Hz), but the real pole may be adjusted by an external capacitor connected to pin VFLTINP. The filter output (pin VFLTOUT) depends on the duty factor of the PWM signals only. A 3-level mode line (VPCNTL) has been included that will: * Enable VCM drivers; VPCNTL = VCC5 (normal) * Disable VCM drivers; VPCNTL = 0.5VCC5 or high impedance * Park (soft retract the actuator); VPCNTL = 0 V.

Their duty factor is converted to a voltage at pin VFLTOUT. At a 100% duty factor the VFLTINP voltage is approximately 1 V above Vrefout. At a 0% duty factor the VFLTINP voltage is approximately 1 V below Vrefout. At a 50% duty factor, the voltage level is equal to Vrefout (typically 4 V). The VFLTINP voltage is amplified, filtered and output at VFLTOUT. The voltage at VFLTOUT varies between 2 V about Vrefout. The VFLTOUT voltage, in conjunction with the sense resistor amplifier, drives the two VCM drivers as illustrated in Fig.4. The equation describing the transconductance from VFLTINP to Icoil is: I coil G m = ------------------------------------------V VFLTINP - V refout 2I coil = ---------------------------------------------------( V VFLTOUT - V refout ) 1 R2 1 = 2 x ---------- x ------- x -------- A/V gain R1 RS TDA5147CH In a typical application: I coil 2 6.6 k 1 -------------------------------------------- = -- x ----------------- x ---------- = 1 A/V V FLTINP - V refout 4 10 k 0.33 The transconductance is variable by selecting external resistors R2/R1 and sense resistors RS. handbook, full pagewidth Vrefout R R VIPWML 1 VIPWMH 2 VFLTINP 3 PWM DEC BUFFER 4 VFLTOUT R1 Vrefout VCMINP 45 R R2 0.5 VCCV12 59 VCMN R ICOIL 51 VCMP RS M voice coil motor 4R V1 V1 R VISENS1 61 60 VISENL 57 VISENH R 4R Vrefout MGG846 Fig.4 Transconductance model. 1997 Jul 09 10 Philips Semiconductors Preliminary specification 12 V Voice Coil Motor (VCM) driver and spindle motor drive combination chip DISABLE VCM DRIVERS With the VPCNTL signal at 0.5VCC the VCM drivers are disabled while the rest of the circuits remain enabled. A sleep mode is initiated when the spindle and VCM are disabled (this places the TDA5147CH in its lowest power setting). ACTUATOR PARK Retracting the actuator can be accomplished by driving VPCNTL LOW in conjunction with either the spindle turning or a brake voltage has been applied. An adjustable retract voltage of 1.2 V (max.) is applied between the VCMN and VCMP outputs. The retract circuit obtains its retract current from the spindle BEMF (pins SHPWR2 and SHPWR3). The retract voltage is determined by two external resistors. One end is connected to pin VCMN and the other to ground. The common point is connected to pin RETADJ (see Fig.8 for additional information). TDA5147CH The calculation of VRETRACT is as follows: R1 + R2 R2 V RETRACT = V BE x --------------------- + --------------- R1 - 50 k VBE = 0.65 V at 25 C and VBE/T = -2 mV/C, 50 k can vary by 30%. It should be noted that R2 has to be less than 10 k. Pin RETADJ can be pulled to ground by applying 0.7 V (VBE) on pin BRKTC. This is used to perform spindle brake during power down. When pin 35 (RETADJ) is pulled to ground, no regulation of the VCMN is taking place, but the VCMP output is still kept LOW. In that case, the SHPWR2 and SHPWR3 lines are loaded with the VCM motor by means of an internal MOS transistor. handbook, full pagewidth Vref VIPWMH LEVEL CONVERTOR SUM UNITY GAIN LOW-PASS VFLTOUT VIPWML LEVEL CONVERTOR 32 : 1 ATTENUATION MBH019 Fig.5 Block diagram of the VCM driver PWM filter.

The PORN (active LOW) logic line is set HIGH following a supply voltage rise above a specified voltage threshold plus a hysteresis, and delayed by a time tC that is controlled by an external capacitor. This PORN signal should remain HIGH until either the +5 or +12 V supplies drop below the voltage threshold, at which point the PORN line should be asserted LOW. The tC timing is set by the following equation: tC C x V th = -----------------I TDA5147CH During a power-down situation the Power-on reset circuit must not only generate a PORN output signal, but must also activate the VCM retract circuitry. In doing so, the VCM driver draws power from SHPWR2 and SHPWR3 during spin-down, and uses this power to bias the VCM against one of the hard stops of the actuator. This prevents the heads from landing on data zones. This BEMF supply is isolated from the supply voltage for the drive, and is half-wave rectified. An external retract capacitor is used to provide the supply voltage for the retract circuit (SHPWR1). It should be noted that in both power-down retract and command retract situations, the voltage across the VCM can be adjusted (RETADJ pin) to limit the velocity of the actuator. The status of both the VCM driver blocks and the spindle driver blocks is shown in Tables 5 and 6. Where Vth = 2.5 V and I is 12 A (typ.). A negative going pulse width of 5 s on either the +5 or +12 V rail will provide a full output pulse. If another trigger pulse occurs before the output is completed a new output pulse will be originated. This implies the Power-on reset circuit is a retriggerable one-shot with a maximum trigger pulse of 5 s (see Fig.7). handbook, full pagewidth VCC Vhys MGG848 threshold 0.8 V t PORN tC tC t Fig.6 Power-on reset timing. 1997 Jul 09 12 Philips Semiconductors Preliminary specification 12 V Voice Coil Motor (VCM) driver and spindle motor drive combination chip SLEEP MODE TDA5147CH threshold VCC 1V hysteresis slopes 1 s/V 5 s A sleep mode is used to save power when the spindle drivers and the VCM drivers are in a disabled state. These two conditions automatically turn off all drivers and amplifiers that are not required. The total power dissipation is approximately 100 mW. The sleep mode is activated when both the spindle (SCNTL1, 2 and 3 are LOW) and the VCM are disabled (VPCNTL left open-circuit). THERMAL SHUTDOWN When the TDA5147CH junction temperature is greater than 150 C all power drivers will be automatically disabled. This is to ensure that no fire hazard occurs due to chip overheating.

OUTLINE VERSION SOT393-1 REFERENCES IEC JEDEC MS-022 EIAJ EUROPEAN PROJECTION ISSUE DATE 94-06-22 96-05-21 1997 Jul 09 27 Philips Semiconductors Preliminary specification 12 V Voice Coil Motor (VCM) driver and spindle motor drive combination chip SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). Reflow soldering Reflow soldering techniques are suitable for all QFP packages. The choice of heating method may be influenced by larger plastic QFP packages (44 leads, or more). If infrared or vapour phase heating is used and the large packages are not absolutely dry (less than 0.1% moisture content by weight), vaporization of the small amount of moisture in them can cause cracking of the plastic body. For more information, refer to the Drypack chapter in our "Quality Reference Handbook" (order code 9397 750 00192). Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. Wave soldering Wave soldering is not recommended for QFP packages. This is because of the likelihood of solder bridging due to closely-spaced leads and the possibility of incomplete solder penetration in multi-lead devices. TDA5147CH If wave soldering cannot be avoided, the following conditions must be observed: * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. * The footprint must be at an angle of 45 to the board direction and must incorporate solder thieves downstream and at the side corners. Even with these conditions, do not consider wave soldering the following packages: QFP52 (SOT379-1), QFP100 (SOT317-1), QFP100 (SOT317-2), QFP100 (SOT382-1) or QFP160 (SOT322-1). During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 C within 6 seconds. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Repairing soldered joints Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C. 1997 Jul 09 28 Philips Semiconductors Preliminary specification 12 V Voice Coil Motor (VCM) driver and spindle motor drive combination chip DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values TDA5147CH This data sheet contains target or goal specifications for product development.
