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

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.
