Description
The bipolar integrated circuit U6043B 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: ≥ 1 W
• Very Low Susceptibility to EMI
• Protection According to ISO/TR 7637/1 Level 4
