CAT4008

8-Channel Constant Current LED Driver

FEATURES

DESCRIPTION

8 Constant current-sink channels

Serial interface up to 25MHz clock frequency

3V to 5.5V logic supply

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 0.4V

(for 2 to 100mA LED current) allows for more power

efficient designs.

LED current range from 2mA to 100mA

LED current set by external RSET resistor

300mV LED dropout at 30mA

Thermal shutdown protection

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

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.

Available in RoHS-compliant 16-lead SOIC (150

and 300mil wide), and TSSOP packages

APPLICATIONS

Billboard Display

Marquee Display

Instrument Display

General Purpose Display

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.

For Ordering Information details, see page 13.
