ACTIVATED IN THE FOLLOWING

CONDITION:

DESCRIPTION

The car radio diagnostic processor is an interface

chip in BCD Technology intended for car radio appli-

cations. It is able to detect potential faults coming

from any misconnection in the car radio or in the har-

ness when installing the set.

- audio channel shorted to V

- audio channel shorted to GND

- aux input shorted to GND

■ NOISE FREE DIAGNOSTICS OPERATION

■ PROTECTORS

■ LOAD DUMP VOLTAGE

■ OPEN GND

The device is able to reveal any fault in the loud-

speaker lines and in the antenna and booster supply

lines, providing a proper output signal (I2C bus com-

patible) in order to disable the ICs under fault and/or

to alert the micro-controller by means of warning

messages.

■ REVERSED BATTERY

■ ESD
