DUAL/QUAD POWER
AMPLIFIER FOR CAR RADIO
DESCRIPTION
The UTC TDA7377 is a class AB car radio amplifier for car
radio, it can 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 few external components. 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.

TYPICAL APPLICATION INFORMATION
Diagnostics Facility note:
UTC TDA7377 built in a diagnostic circuitry, when following events appearing: clipping in the output signal,
thermal shutdown, and output fault including short to GND, short to VS and soft short at turn on.
When the event is detected, The information is available across an open collector output (pin 10) through a current
sinking (see Fig 4).The current sinking at pin 10 is triggered when a certain distortion level is reached at any of the
outputs. This function allows gain compression possibility whenever the amplifier is overdriven. The current sinking
at pin 10 also can be triggered When the IC’s operating temperature raise to about 10°C before the shutdown
threshold.
Normally the clip detector signaling produces a low level at pin 10 that is shorter than that present under faulty
conditions; This can be used to discriminate each event (clipping detection, output fault, thermal proximity).
