Fig.4 Pin configuration (SOT418-2). 1999 Apr 08 7 Philips Semiconductors Preliminary specification Power amplifier with load detection and auto BTL/SE selection FUNCTIONAL DESCRIPTION The TDA8586 is a multi-purpose power amplifier with four amplifiers and 2 buffer stages, which can be connected in the following configurations with high output power and low distortion: * Dual Bridge-Tied Load (BTL) amplifiers * Quad Single-Ended (SE) amplifiers. In the BTL mode of operation, the 2 buffer amplifiers act as inverting amplifiers to complete the bridge across the `front' amplifiers (OUT1 and OUT3) and the `rear' outputs (OUT2 and OUT4) enter a high-impedance state. In the SE mode of operation, the buffers act as an AC ground path thereby eliminating the need for series capacitors on the speaker outputs. Diagnostics: * While the IC is in the mute mode, the diagnostic output will signal the mode of operation when the IC is not overruled * In the on mode the diagnostic output will signal any fault in the IC or if the output of any amplifier is clipping with a distortion of 10% (or 2% depending on selected clip-mode). Special attention is given to the dynamic behaviour as follows: * Noise suppression during engine start * No plops when switching from standby to on * Slow offset change between mute and on (controlled by MSO pin) * Low noise levels, which are independent of the supply voltage. Protections are included to avoid the IC being damaged at: * Over temperature: Tj > 150 C * Short-circuit of the output pin(s) to ground or supply rail. When short-circuited, the power dissipation is limited * ESD protection (Human Body Model 3000 V and Machine Model 300 V). TDA8586 The presence of the load is measured after the transition between standby and mute. The IC will determine if there is an acceptable load on both outputs (OUT2 and OUT4). If both outputs are unloaded, the IC will switch to a 2 speaker mode of operation (BTL mode), unless it is overruled. There are two options to overrule: 1. Before transition from mute to on, after a load detection, pulling the diagnostic output above 9.5 V will force the IC into 4 speaker mode 2. TDA8586TH: pulling the OVERRULE pin according pinning table. Care should be taken with the OVERRULE function as it works during the on mode. If there is a 2 or 4 speaker mode change during the on mode a large `plop' can be heard on the speakers. The ACREF input (common signal input) acts with the four signal inputs (IN1 to IN4) to provide quasi differential inputs. A capacitor must be connected to this pin of which the ground pin should be connected to the ground at the signal source (usually the ground at the audio signal processor). This capacitor has a dual function. During the speaker detection, the signal ground capacitor is used to set the time constant of the measurement (and thus determines the minimum required switch-on time). The capacitor on the MSO pin allows the integrate function to provide immunity to outside noises during load detection. 1999 Apr 08 8 Philips Semiconductors Preliminary specification Power amplifier with load detection and auto BTL/SE selection TDA8586 handbook, full pagewidth state condition standby mute load detect mute no load detect on no clipping/shorts on clipping on short-circuit VP VP 0 minimum 1 s 9V MSO SE detection 3V 0 BTL detection 5V diagnostic information 0 BTL detected SE detected 10 V diagnostic overrule 0 5V mode select 0 The mode is overruled only from BTL to SE when the diagnostic pin is excited with a pulse of 10 V.

A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mount components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mount ICs, or for printed-circuit boards with high population densities. In these situations reflow soldering is often used. Through-hole mount packages SOLDERING BY DIPPING OR BY SOLDER WAVE The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joints for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg(max)). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. MANUAL SOLDERING Apply the soldering iron (24 V or less) to the lead(s) of the package, either below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 C, contact may be up to 5 seconds. Surface mount packages REFLOW SOLDERING 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 methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. 1999 Apr 08 21 MANUAL SOLDERING TDA8586 Typical reflow peak temperatures range from 215 to 250 C. The top-surface temperature of the packages should preferable be kept below 230 C. WAVE SOLDERING Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was specifically developed. If wave soldering is used the following conditions must be observed for optimal results: * Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. * For packages with leads on two sides and a pitch (e): - larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; - smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves at the downstream end. * For packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side 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. 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. Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron 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. Philips Semiconductors Preliminary specification Power amplifier with load detection and auto BTL/SE selection Suitability of IC packages for wave, reflow and dipping soldering methods TDA8586 SOLDERING METHOD MOUNTING PACKAGE WAVE Through-hole mount DBS, DIP, HDIP, SDIP, SIL Surface mount BGA, SQFP HLQFP, HSQFP, HSOP, HTSSOP, SMS PLCC(4), SO, SOJ LQFP, QFP, TQFP SSOP, TSSOP, VSO Notes 1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the "Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods". 2. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board. 3. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 4. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 5. Wave soldering is only suitable for LQFP, QFP and TQFP packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 6. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
