INTEGRATED CIRCUITS DATA SHEET TDA1515BQ 24 W BTL or 2 x 12 W stereo car radio power amplifier Product specification File under Integrated Circuits, IC01 July 1994 Philips Semiconductors Product specification 24 W BTL or 2 x 12 W stereo car radio power amplifier TDA1515BQ The TDA1515BQ is a monolithic integrated class-B output amplifier in a 13-lead single in-line (SIL) plastic power package. The device is primarily developed for car radio applications, and also to drive low-impedance loads (down to 1,6 Ω). At a supply voltage VP = 14,4 V, an output power of 24 W can be delivered into a 4 Ω BTL (Bridge Tied Load), or, when used as stereo amplifier, it delivers 2 × 12 W into 2 Ω or 2 × 7 W into 4 Ω. Special features are: • flexibility in use − mono BTL as well as stereo • high output power • low offset voltage at the output (important for BTL) • large usable gain variation • very good ripple rejection • internal limited bandwidth for high frequencies • low stand-by current possibility (typ. 1 µA), to simplify required switches; TTL drive possible • low number and small sized external components • high reliability. The following currently required protections are incorporated in the circuit. These protections also have positive influence on reliability in the applications. • load dump protection • a.c. and d.c. short-circuit safe to ground up to VP = 18 V • thermal protection • speaker protection in bridge configuration • SOAR protection • outputs short-circuit safe to ground in BTL • reverse polarity safe.

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. 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. Repairing soldered joints Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, 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. 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). Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds.
