CAT4002A Product details

Description

The CAT4002A and CAT4004A provide respectively two and four matched low dropout current sources to drive LEDs.The CAT400XA 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
