CAT4008

8-Channel Constant Current

LED Driver

Description

The CAT4008 is an 8 channel constant current driver for LED

billboard and other general display applications. LED channel

currents are programmed together via an external RSET resistor. Low

output voltage operation on the LED channels as low as 0.4 V (for 2 to

100 mA LED current) allows for more power efficient designs.

A high−speed 4−wire serial interface of up to 25 MHz clock

frequency controls each individual channel using a shift register and

latch configuration. A serial output data pin (SOUT) allows multiple

devices to be cascaded and programmed via one serial interface. The

device also includes a blanking control pin (BLANK) that can be used

to disable all channels independently of the interface.

Thermal shutdown protection is incorporated in the device to

disable the LED outputs if the die temperature exceeds a set limit.

The device is available in the 16−lead SOIC (narrow and wide), and

TSSOP packages.
