1 / 12 page October 2007 Rev 1 1/12 1 TDA7854 4 x 47W MOSFET quad bridge power amplifier Features ■ Multipower BCD technology ■ High output power capability: –4 x 47W/4 Ω max. –4 x 80W/2 Ω max. ■ MOSFET output power stage ■ Excellent 2Ω driving capability ■ Hi-fi class distortion ■ Low output noise ■ St-by function ■ Mute function ■ Automute at min. supply voltage detection ■ Low external component count: – Internally fixed gain (26dB) – No external compensation – No bootstrap capacitors Protections: ■ Output short circuit to GND, to Vs, across the load ■ Very inductive loads ■ Overrating chip temperature with soft thermal limiter ■ Load dump voltage ■ Fortuitous open GND ■ Reversed battery ■ ESD Description The TDA7854 is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt 25 package designed for high power car radio. The fully complementary P-Channel/N- Channel output structure allows a rail to rail output voltage swing which, combined with high output current and minimized saturation losses sets new power references in the car-radio field, with unparalleled distortion performances.
