U2043B
WFlasher, 30-m Shunt, Pilot Lamp to GND or VBatt
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 VBatt or GND.
Features
D Temperature and voltage compensated frequency
D Warning indication of lamp failure by means of
frequency doubling
wD Minimum lamp load for flasher operation 10 W
D Relay output with high current carrying capacity and
low saturation voltage
D Low susceptibility to EMI
