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.
