24 W BTL or 2 x 12 W stereo car radio power amplifier

Leave a Comment
General Description:
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. 

Features:
  • 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.
  • he 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.

GENERAL DESCRIPTION:
The TDA1518BQ is an 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.
 FEATURES:
  • Requires very few external components
  • Flexibility in use  stereo as well as mono BTL
  • High output power (without bootstrap)
  • Low offset voltage at output (important for BTL)
  • Fixed gain
  • Good ripple rejection
  • Mute/stand-by switch
  • Load dump protection
  • A.C. and d.c. short-circuit-safe to ground and VP
  • Thermally protected
  • Reverse polarity safe
  • Capability to handle high energy on outputs (VP = 0 V)
  • No switch-on/switch-off plop
  • Flexible leads
  • Low thermal resistance
  • Identical inputs (inverting and non-inverting)
  • Compatible with TDA1516BQ (except gain).
