Overview
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 TSSOP package.
