STPA001 4 x 50 W MOSFET quad bridge power amplifier Datasheet - production data Internally fixed gain (26 dB) Protections: Output short circuit to GND, to Vs, across the load Very inductive loads Flexiwatt27 (Vertical) Flexiwatt27 (Horizontal) Overrating chip temperature with soft thermal limiter Output DC offset detection Load dump Fortuitous open GND 0 03 Reversed battery Flexiwatt25 (Vertical) Flexiwatt25 (Horizontal) ESD Capable to operate down to 6 V (e.g. Startstop) Features Multipower BCD technology Description High output power capability: The STPA001 is a breakthrough MOSFET 4 x 50 W/4 Max. technology class AB audio power amplifier 4 x 28 W/4 14.4 V, 1 kHz, 10 % designed for high power car radio. The fully 4 x 72 W/2 Max. complementary P-Channel/N-Channel output MOSFET output power stage structure allows a rail to rail output voltage swing which, combined with high output current and 2 driving capability minimized saturation losses sets new power Hi-Fi class distortion references in the car-radio field, with unparalleled Low output noise distortion performances. High immunity to RF noise injection The STP A001 can operate down to 6 V and this makes the IC compliant to the most recent OEM Standby function specifications for low voltage operation (so called Mute function start-stop battery profile during engine stop), Automute at min. supply voltage detection helping car manufacturers to reduce the overall emissions and thus contributing to environment Low external component count protection.
