45 W AF POWER AMPLIFIER

DESCRIPTION

The uPC2500A is an audio power amplifier in a 12-lead single in-line package, specifically designed for car stereo appli- cations. Typically it provides output power of 45 W at 14.4 V or 40 W at 13.2 V to a2 2 load. This IC can be used without output capacitors, because its two output terminals have the same potential and it includes original short circuit protection function which protects internal output power transistors and a speaker at the same time when one output terminal is shorted to ground or Vec.

FEATURES

®@ Internal stand-by switch circuit; CMOS drive possible. © Can be used as OCL connection. © Very low output offset voltage : Vottser = 150 mV (MAX.) ® High output power: Po =45 W(TYP.) @ Ry =2Q, Voc = 14.4 V, THD = 10% Po =40 W(TYP.) @ Ry = 22, Voc = 13.2 V, THD = 10 % © Very low distortion: THD =0.03 % (TYP.) @R, =2Q, Voc = 13.2 V, Po = 8 W, f = 1 kHz © Following protection circuits are included. (1) Load dump voltage surge protection circuit. (2) Thermal shut down protection circuit. {3) Output terminal short circuit protection circuit. (Vec¢ to OUT, OUT to GND, OUT to OUT) (4) Loudspeaker protection circuit.
