SiTi DM631B

DM631B is a 16-channel constant current sink LED driver. Each channel has independent 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, and built-in LED open detection circuit to detect error status.
