The CAT4002ASD-GT3 is a constant current LED driver designed to provide two matched low dropout current sources for driving LEDs. It utilizes an external resistor (RSET) to set the current in the LED channels, allowing for flexibility in LED forward voltage handling while maintaining tight current matching. The device supports 32 linear dimming levels through its EN/DIM logic inputs, enabling both device enablement and digital dimming control. This LED driver operates with a low dropout voltage of 50 mV at 20 mA, making it suitable for direct connection to Lithium-ion batteries. The CAT4002ASD-GT3 is available in compact packages, specifically an 8-pad UDFN measuring 2 mm x 2 mm and a 6-lead SC-70. It features thermal shutdown protection and has a shutdown current of less than 1 ¬µA, ensuring efficient operation. The recommended operating voltage range is from 2.4 V to 5.5 V, with an ambient temperature range of -40¬8C to +85¬8C. The device is compliant with RoHS standards, being Pb-free and halogen-free.
