The CAT4002B provides two matched low dropout current sources to drive LEDs. The CAT4002B requires no external RSET resistor; the LED current is internally set to 25 mA when the device is first enabled. 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 input supports the 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 (75 mV at 20 mA) current sinks. Available with 2-channel in the 6-lead TSOT-23 and SC-70 packages.
