DESCRIPTION 

The YD7377 is a new technology class AB car radio amplifier able to work either in DUAL BRIDGE or QUAD SINGLE ENDED configuration. The exclusive fully complementary structure of the output stage and the internally fixed gain guarantees the highest possible power performances with extremely reduced component count. The on-board clip detector simplifies gain compression operation. The fault diagnostics makes it possible to detect mistakes during car radio set assembly and wiring in the car.

Protections:

• OUPUT AC/DC SHORT CIRCUIT

  – TO GND

  – TO VS 

  – ACROSS THE LOAD 

• SOFT SHORT AT TURN-ON 

• OVERRATING CHIP TEMPERATURE WITH SOFT THERMAL LIMITER 

• LOAD DUMP VOLTAGE SURGE 

• VERY INDUCTIVE LOADS 

• FORTUITOUS OPEN GND 

• REVERSED BATTERY 

• ESD
