■ Low output noise

■ Standby function

■ Mute function

– Fortuitous open GND

– Reversed battery

– ESD

■ Automute at min. supply voltage detection

■ Low external component count:

– Internally fixed gain (26 dB)

– No external compensation

– No bootstrap capacitors

Description

The TDA7851A is a breakthrough MOSFET

technology class AB audio power amplifier,

designed for high-power car radio.

■ Protections:

– Output short circuit to GND, to Vs, across

the load

The fully complementary P-Channel/N-Channel

output structure allows a rail-to-rail output voltage

swing. This, combined with high output current

and minimized saturation losses, sets new power

references in the car-radio field, with unparalleled

distortion performance.

– Very inductive loads

– Overrating chip temperature with soft

thermal limiter

– Output DC offset detection

– Load dump voltage
