Cxle87142 is a single line three channel LED constant current drive special circuit which is internally integrated with MCU single line digital interface data latch LED constant current drive

It can be cascaded through two channel input and output digital interfaces, and the external controller only needs a single line to control the chip. The standby communication port can realize the damage of a chip in the cascade without affecting the normal use of the later stage. The constant current value and PWM brightness value output by each out drive port can be set separately by command. This product has excellent performance and reliable quality
