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
