■ MOSFET output power stage

■ Capable to operate in low voltage conditions

■ Output DC offset detection

■ Load dump voltage

■ Fortuitous open GND

■ Reversed battery

■ ESD

(e.g.: “Start - Slop”)

■ Excellent 2 Ω driving capability

■ Hi-Fi class distortion

■ Low output noise

■ Standby function and mute function

■ Automute at min. supply voltage detection

Description

■ Low external component count:

– Internally fixed gain (26 dB)

– No external compensation

– No bootstrap capacitors

The TDA7850LV is a MOSFET class AB audio

power amplifier, designed for high-power car

radio. In addition to the outstanding output current

capability and distortion performance, the

TDA7850LV is extremely robust against several

kinds of fortuitous misconnections.

■ On board 0.35 A high side driver

Protections:

It is, moreover, compliant to the most recent OEM

specifications for low voltage operation (the so

called 'start-stop' battery profile during engine

stop) and features a very compact design in BCD

technology.

■ Extreme robustness against any kind of short

to GND

■ Output short circuit to GND, to V , across the

load

The TDA7850LV includes offset detector

capability (or high side driver output) and is

available in both SMD and standard Flexiwatt

packages.

■ Very inductive loads

■ Overrating chip temperature with soft thermal

limiter
