T he AD22001 is a monolithic, five-channel comparator circuit
for monitoring the functionality of lamps in automotive
applications.
T he IC tests the series circuit leading to the lamp to determine
if the circuit is intact and a functional lamp is in the socket. T he
AD22001 continuously checks the functionality of up to five
bulbs in either their “on” or “off” state, and also tests for the
presence of an in-line fuse in two of the series circuits.
Digital outputs indicate the status of each channel. Additionally,
the AD22001 provides a voltage limited power supply output to
supply 15 V CMOS circuits that may interface to the AD22001.
