... Relay Output with High Current Carrying Capacity and Low Saturation Voltage • Low Susceptibility to EMI 1. 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. The pilot lamp can be connected either GND. ...
