24 W BTL or 2 x 12 W stereo
TDA1515BQ
car radio power amplifier
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.
