U2043B Datasheet PDF - ATMEL

●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 to VBatt or GND.

●Features

●• Temperature and Voltage Compensated Frequency

●• Warning Indication of Lamp Failure by Means of Frequency Doubling

●• Minimum Lamp Load for Flasher Operation ≥10W

●• Relay Output with High Current Carrying Capacity and Low Saturation Voltage

●• Low Susceptibility to EMI
