Description	Automotive Lamp Outage Monitor/ VT = 8 mV
Datasheet	U479B_TEMICSemiconductors.pdf

The monolithic integrated bipolar circuit, U479B, is designed as a monitor for lamp failure in automobiles.

The parator threshold is matched to the PTC characteristic of incandescent lamps.

The threshold is tied to V4,6 = VS – VT whereas VT = 8 mV.

D D D D 2 kV.
ESD protection Two comparators with common reference Tight threshold tolerance Threshold matched to PTC characteristic of incandescent lamps D NPN output D Interference and damage.
protection according to VDE 0839 D Temperature compensated D EMI protection D Reversal polarity protection D Load-dump protection Ordering Information Extended Type Number U479B U479B.
