GENERAL DESCRIPTION APPLICATIONS * Hard disk drive for PC products. * Retract circuit operates down to 2 V TDA5147K * Internal thermal sense circuitry with an over temperature shut down option * Internal boost voltage generator * Sleep mode. The TDA5147K is an ASIC combination chip that includes the following functions; spindle motor drive, voice coil motor drive, retract, and power-on. The circuit is contained in a 52-pin PLCC package. The TDA5147K (see Fig.1) is controlled by a custom digital ASIC. 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 the SIPWM pin). Control of the VCM circuits is via the VIPWMH and VIPWML input signals. These two inputs provide control of the coil current. The VISENSE2 output signal can be used to monitor the voice coil current.

Back EMF (BEMF) sensing of the commutation rate needs to be output to an external digital ASIC circuit. This digital circuit also provides the input commutation control. Consequently, all speed control, start-up routine and commutation control will be generated by the 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 is duty factor dependent only. The filter characteristics is that of a 1-pole low-pass filter, with the pole location being controlled by the external capacitor connected to pin SPWMFLT. Dynamic braking is possible only during non power-down situations and must be initiated by the digital circuit. SMODE1 A 3-state level mode line (SMODE1) has been included to allow for; 1. An induction sensing algorithm in pre-start-up (VCCA1). 2. PWM control during start-up (0.5VCCA1). 3. Linear control (0 V). SENSING MODE The induction sensing mode is used for two purposes. Firstly one of the BEMF sensor outputs (SENWIS) will be shared with the voltage comparator that is used for the induction sensing function. Prior to start-up each phase can be 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. Secondly, in situations where the spindle motor requires more current to spin-up, this mode is used with the exception that the output SENWIS is ignored. Since, in the induction sense mode, the output drivers are operated in saturation mode, the motor current is limited only by the power supply. This condition of induction sense mode can be used to overcome the head friction and must be used only when needed. PWM MODE The PWM mode is normally used during the start-up phase. Maximum drive voltage is applied to the low drivers TDA5147K to obtain high start-up torque. The purpose of the PWM mode is to drive the low drivers into saturation (saturation reduces the power dissipation in the TDA5147K during start-up). When the spindle current reaches the programmed set current (SIPWM) value, a one-shot is fired. The output of the one-shot remains high for the programmed off-time (toff) set by the capacitor/resistor network at the SPWMTC pin. The one-shot is not retriggerable for approximately 10% of the off-time, this gives a minimum of (10% toff) time-on. During the off-time, the lower spindle output drivers are switched off. The on-time of the drivers is not fixed but is determined by the charging time of the coil current to reach the program set current. The turn-off time is calculated by the equation: toff = R x Cln(2) Where R = 68 k and C = 220 pF, toff = 10.4 s. The minimum on-time can be calculated by the equation: CV 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 linear 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 1 V SISENH 1 1 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: 1 0% duty 0% duty 1 1 I coil = ------ = -- x 1.74 x -------------------- = ------ ( 0.348 ) x -------------------Rs 100 100 5 Rs 1996 Jul 26 8 Philips Semiconductors Product specification 12 V Voice Coil Motor (VCM) driver and spindle motor drive combination chip TDA5147K 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. Table 1 Input decoder truth table CONDITION Disable Dynamic brake State 1 State 2 State 3 State 4 State 5 State 6 Under voltage Note 1. X = 3-state. VCM driver The VCM driver is a linear, class AB, H-bridge type power driver with all power devices internal to the chip. In addition to the power stage a sense resistor enables VCM current to be measured and brought out to a separate ADC via the VISENS2 pin. The reference voltage for the VISENS2 output is provided externally. The current level to the VCM is controlled via two PWM signals that are generated by the digital circuit. The input voltage at pin 47 (VIPWMH) represents a weighting of 32 times more than the input voltage at pin 46 (VIPWML), thus the current command is equal to 32 x duty factor (VIPWML + VIPWMH). These PWM signals are filtered by an internal 3rd-order low-pass filter (Butterworth filter). The bandwidth of this low-pass filter is nominally 40 kHz (less than 2 degrees lag at 500 Hz), but the real pole may be adjustable by an external capacitor. The analog output of the filter depends on the duty factor of the PWM signal and not on the logic level.

Enable VCM drivers; VCCA1 (normal). 2. Disable VCM drivers; 0.5VCCA1. 3. PARK (soft retract the actuator); 0 V. Enable VCM drivers When the enable signal is HIGH, the VCM drivers are controlled by the two PWM inputs. The two digital signals convert the duty factor to a voltage level at VFLTOUT. At a 100% duty factor the VFLTINP voltage is approximately 1 V above Vref(o). At a 0% duty factor the VFLTINP voltage is approximately -1 V below Vref(o). At a 50% duty factor, the voltage level is equal to Vref(o) (typical 4 V). The VFLTINP voltage is amplified, filtered and output at VFLTOUT. The voltage at VFLTOUT varies between 2 V about Vref(o). The VFLTOUT voltage, in conjunction with the sense resistor amplifier, drives the two VCM drivers as illustrated in Fig.8. The transconductance equation that governs the voltage from VFLTINP to Icoil is: I coil I coil G m = -------------------------------------------- = ----------------------------------------------------V FLTINP - V ref ( o ) ( V FLTOUT - V ref ( o ) ) 1 R2 1 = 2 x ----------- x ------- x ------ Amps per Volt gain R1 R s In a typical application: I coil 2 6.6 k 1 -------------------------------------------- = -- x ----------------- x ---------- = 1 Amp per Volt -V FLTINP - V ref ( o ) 4 10 k 0.33 The transconductance is variable by selecting external resistors R2/R1 and sense resistors Rs Disable VCM drivers With the PARK enable signal at 0.5V 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 TDA5147K in its lowest power setting). ACTUATOR PARK TDA5147K Retracting the actuator can be accomplished by driving VPCNTL LOW in conjunction with either the spindle is 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 SDRVU phase. If the SDRVU phase is zero there will be no retract voltage. The retract voltage is determined by two external resistors. One end is tied to VCMN and the other to ground. The common point is tied to pin 22 (RETADJ); see Fig.1 for additional information. The calculation of VRETRACT is as follows: 1 + R2 R2 V RETRACT = 0.65 x ----------------- + --------------- R1 50 k Where 0.65 is VBE at 25 C VBE/T = -2 mV/C; 50 k can vary by 30% It should be noted that R2 has to be less than 10 k. Power-on reset The power-on reset circuit monitors the voltage levels of both the +5 V and the +12 V supply voltages as shown in Fig.6. The POR (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 POR signal should remain HIGH until either the +5 or +12 V supplies drop below the voltage threshold, at which point the POR line should be asserted LOW. The tC timing is set by the following equation: C x V th t C = -----------------I 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). 1996 Jul 26 10 Philips Semiconductors Product specification 12 V Voice Coil Motor (VCM) driver and spindle motor drive combination chip TDA5147K handbook, full pagewidth VCC Vhys MBH021 threshold 0.8 V t POR tC tC t Fig.6 Power-on reset timing. handbook, full pagewidth threshold VCC 1V hysteresis slopes 1 s/V 5 s POR tC MBH020 Fig.7 Trigger pulse requirement. 1996 Jul 26 11 Philips Semiconductors Product specification 12 V Voice Coil Motor (VCM) driver and spindle motor drive combination chip During a power-down situation the power-on reset circuit must not only generate a POR output signal, but must also activate the VCM retract circuitry. In doing so, the VCM driver draws power from the BEMF of the SDRVU output 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. It should be noted that in both power-down retract and command retract situations, the voltage across the VCM is nominally limited to 1.2 V (to limit the velocity of the actuator). Additional information is given in Fig.6. SLEEP MODE TDA5147K 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 is disabled (SCNTL1, 2 and 3 = 0) and the VCM is disabled (VPCNTL left open-circuit). THERMAL SHUTDOWN When the TDA5147K chip 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.

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 PLCC packages. The choice of heating method may be influenced by larger PLCC 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 TDA5147K Wave soldering techniques can be used for all PLCC packages if the following conditions are observed: * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. * The longitudinal axis of the package footprint must be parallel to the solder flow. * The package footprint must incorporate solder thieves at the downstream corners. 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. 1996 Jul 26 27 Philips Semiconductors Product 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 TDA5147K This data sheet contains target or goal specifications for product development.
