    Products Detail

    The U6433B is an automotive flasher IC designed for car indicator lamps with temperature and voltage compensated frequency. It features lamp failure detection via frequency doubling, a high-current relay output with low saturation voltage, load-dump protection, and very low EMI susceptibility. The device includes a 49-mV comparator for lamp failure detection and an 8-mV comparator for frequency doubling control, with protection according to ISO/TR 7637/1 Level 4. It operates with a minimum lamp load of 1W and provides accurate monitoring via an external shunt resistor.

    Key Features

    • Temperature and Voltage Compensated Frequency, Warning Indication of Lamp Failure by Means of Frequency Doubling can be Disabled, Voltage Dependence of the Car Indicator Lamps Compensated for Lamp Failure, Relay Output with High Current Carrying Capacity and Low Saturation Voltage, Minimum Lamp Load for Flasher Operation ≥ 1W, Load-dump Protection Flasher, 18-mΩ, Very Low Susceptibility to EMI, Protection According to ISO/TR 7637/1 Level 4 Shunt, Frequency Doubling Disabling
