BCT3119 Overview
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.
BCT3119 Key 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 mon-anode LEDs
- High data input rate: < 20MHz
- 2.7V to 5.5V Supply Voltage Range
- RoHS pliant and 100% Lead (Pb)-Free
