Cxle87143 is a nine channel led fixed constant current drive control special circuit which is internally integrated with MCU single line digital interface data latch led fixed constant current drive

The chip can be cascaded through a single line digital interface (DI, do). The external controller only needs a single line to control the chip and the subsequent chips cascaded with it. The PWM brightness of the cxle87143 output port can be set independently through the external controller. The VDD pin is internally integrated with 5V regulator and few peripheral devices. This product has excellent performance and reliable quality.
