Constant Current

Programmable LED Driver

with 32 Dimming Levels

Description

http://onsemi.com

The CAT4002B, CAT4003B and CAT4004B provide respectively

two, three and four matched low dropout current sources to drive

LEDs. The CAT400XB 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.

Package options are available including the 4−channel tiny 8−pad

UDFN 2 mm x 2 mm with a max height of 0.55 mm, and 2 or 3−

channel in the 6−lead TSOT−23 and SC−70.
