Description
●The bipolar integrated circuit U643B is used in relay-controlled automotive flashers where a high-level EMC is required.
●Lamp outage is indicated by frequency doubling during hazard warning as well as direction mode.
●Features
●• Temperature and Supply Voltage Compensated Flashing Frequency
●• Frequency Doubling Indicates Lamp Outage
●• Relay Driver Output with High Current Carrying Capacity and Low Saturation Voltage
●• Minimum Lamp Load for Flasher Operation: ≥ 1W
●• Very Low Susceptibility to EMI
●• Protection According to ISO/TR 7637/1 Level 4
