Automotive Lamp Outage Monitor, VT = 8 mV  
Description  
The monolithic integrated bipolar circuit, U479B, is If the voltage drop across shunt resistor, R , exceeds  
sh  
designed as a monitor for lamp failure in automobiles. 8 mV, the output is turned off, otherwise the output is  
The comparator threshold is matched to the PTC turned on. Without supply voltage or open input Pin 8, the  
characteristic of incandescent lamps. The threshold is output is turned off. A not used comparator input must be  
tied to V = V – V whereas V = 8 mV.
