Update: 28 September, 2023
The U2043B is an integrated circuit 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. The pilot lamp can be connected either to VBatt or GND. It features temperature and voltage compensated frequency, warning indication of lamp failure by means of frequency doubling, minimum lamp load for flasher operation, relay output with high current carrying capacity and low saturation voltage, and low susceptibility to EMI.
