Features:

• Few External Components

• No Boucherot Cells

• No Bootstrap Capacitors

• High Output Power

• No Switch ON/OFF Noise

• Very Low Stand–by Current

• Fixed Gain (30dB Stereo)

• Programmable Turn–On Delay



Protections:

• Output AC–DC Short Circuit to GND and to Supply Voltage

• Very Inductive Loads

• Loudspeaker Protection

• Overrating Chip Temperature

• Load Dump Voltage

Part name(s)' : TDA1515 TDA1515BQ
Description : 24 W BTL or 2 x 12 W stereo Car Radio power Amplifier
Philips
Philips Electronics

24 W BTL or 2 x 12 W stereo 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 1,6Ω). At a supply voltage VP= 14,4 V, an output power of 24 W can be delivered into a 4ΩBTL (Bridge Tied Load), or, when used as stereo Amplifier, it delivers 2×12 W into 2Ωor 2×7 W into 4Ω.



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.
