STPA003 4 x 52 W quad bridge power amplifier with high side driver and low voltage operation Datasheet - production data No external compensation No bootstrap capacitors On board 0.4 A high side driver Protections: GAPGPS00070 Output short circuit to GND, to V , across GAPGPS00670 s the load Flexiwatt27 Flexiwatt25 Very inductive loads Overrating chip temperature with soft thermal limiter Output DC offset detection Features Load dump voltage High output power capability: Fortuitous open GND 4 x 52 W/4 max. Reversed battery 4 x 30 W/4 14.4 V, 1 kHz, 10 % ESD 4 x 85 W/2 max. 4 x 55 W/2 14.4V, 1 kHz, 10 % Description MOSFET output power stage The STPA003 is a MOSFET class AB audio Capable to operate in low voltage conditions power amplifier, designed for high-power car (e.g.: Start - Stop) radio. In addition to the outstanding output current Excellent GSM noise immunity capability and distortion performance, the STPA003 is extremely robust against several Excellent 2 driving capability kinds of fortuitous misconnection. Hi-Fi class distortion It is compliant to the most recent OEM Low output noise specifications for low voltage operation (the so Standby function and mute function called start-stop battery profile during engine Automute at min. supply voltage detection stop). Low external component count: It includes a DC offset detector and, in Internally fixed gain (26 dB) Flexiwatt27 package, a high side driver or a clipping detector. Table 1.
