U2043B
Flasher, 30-m
W
Shunt, Pilot Lamp to GND or V
Batt
Description
The integrated circuit U2043B is used in relay controlled
automotive flashers where a high EMC level is required.
A lamp outage is indicated by frequency doubling during
hazard mode as well as direction mode. Pilot lamp can be
connected either to V
Batt
or GND.
