DM631 Datasheet (SiTi) - 16-CHANNEL CONSTANT CURRENT LED DRIVER

DM631, 16-CHANNEL CONSTANT CURRENT LED DRIVER

DM631 is a 16-channel constant current sink LED driver.

Each channel has adjustable 12-bits (4096 steps) grayscale PWM control current outputs.

It incorporates shift registers, data latches, constant current circuitry with current value set by an external resistor, selectable oscillator source for P
