CHANNEL 5  
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.
