TDA7854

TDA7854 4 x 47W MOSFET quad bridge power amplifier Features ■ ■ Multipower BCD technology High output power capability: – 4 x 47W/4Ω max. – 4 x 80W/2Ω max. MOSFET output power stage 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 ■ ■ ■ ■ www.DataSheet4U.com ■ Excellent 2Ω driving capability ■ ■ ■ ■ ■ ■ Flexiwatt 25 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/NChannel 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. Protections: ■ ■ ■ ■ Output short circuit to GND, to Vs, across the load Very inductive loads Overrating chip temperature with soft thermal limiter Load dump voltage Table 1.
