Flexiwatt 25

■ Low output noise

■ Standby function

■ Mute function

■ Fortuitous open GND

■ Automute at min. supply voltage detection

■ Reversed battery

■ ESD

Description

The TDA7851L is a breakthrough MOSFET

technology class AB audio power amplifier in

Flexiwatt25 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.

Protections

■ Output short circuit to Gnd, to Vs, across the

load

■ Very inductive loads

■ Overrating chip temperature with soft thermal

limiter

■ Load dump voltage
