    产品信息

    The CAT4002A provides a two matched low dropout current sources to drive LEDs. The CAT4002A uses an external resistor RSET to set the current in the LED channels. Each LED channel includes an individual control loop allowing the device to handle a wide range of LED forward voltages while still maintaining tight current matching.
    The EN/DIM logic inputs supports device enable and a digital dimming interface for setting the LED channel current with 32 linear dimming levels.
    LEDs can be powered directly from a Lithium-ion battery due to the low dropout (50 mV at 20 mA) current sinks. The device is available in the 6-lead TSOT-23 and SC-70.
    • Low Dropout Driver 50 mV at 20 mA
