BCT3119

May, 2009, REV1.0 BCT3119 9-Channel 64steps Constant-Current LED Driver with SPI Control General Description The BCT3119 is a constant current driver incorporating shift register and data latch. This CMOS device is designed for LED display applications. The max output constant current can be set using an external resistor, and 64 steps of current could be set through a SPI interface with MCU. Any channel output could have any step current levels. Applications Cell Phones Multicolor LED lighting Display backlighting Toys/Mp3/Mp4/CD/minidiskplayers Features ♦ 9 channel constant-current outputs, up to 40mA each ♦ Each channel current could be controlled through a SPI interface with MCU ♦ Power-On Reset(POR), all register bits=0 ♦ For common-anode LEDs ♦ High data input rate: < 20MHz ♦ 2.7V to 5.5V Supply Voltage Range ♦ RoHS Compliant and 100% Lead (Pb)-Free Pin Configurations (Top view) Ordering Information PART BCT3119EGP-TR PIN-PACKAGE QFN-20 （3x3mm） Temp-Ran...
