DM631 Datasheet PDF

SiTi DM631

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 PWM function, and built-in LED open detection circuit to detect error status.
