U4791B fiche technique
U4791B
Automotive Lamp Outage Monitor, VT = 53 mV
Description
The monolithic integrated bipolar circuit, U4791B, is de-
signed as a monitor for lamp failure in automobiles. The
comparator threshold is matched to the PTC
characteristic of incandescent lamps. The threshold is
tied to a typical value of V4,6 = VS – VT whereas
VT = 53 mV.
The integrated circuit is recommended for the application
of parallel connected lamps. If the voltage drop across
shunt resistor, Rsh, exceeds 53 mV, the output is turned
off, otherwise the output is turned on. Without supply
voltage or open input Pin 8 the output is turned off.
A not used comparator must be connected to Pin 7.
