CAT4004A Datasheet Constant Current Led Driver

Manufacturer: onsemi

Overview: Constant Current LED Driver with 32 Dimming Levels and Rset CAT4002A,.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General 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.
