CAT4008 8-Channel Constant Current LED Driver FEATURES „ 8 Constant current-sink channels „ Serial interface up to 25MHz clock frequency „ 3V to 5.5V logic supply „ LED www.DataSheet4U.com current range from 2mA to 100mA „ LED current set by external RSET resistor „ 300mV LED dropout at 30mA „ Thermal shutdown protection „ Available in RoHS-compliant 16-lead SOIC (150 and 300mil wide), and TSSOP packages 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 0.4V (for 2 to 100mA LED current) allows for more power efficient designs.
