General Description

DM632 is a 16-channel constant current sink LED driver.

Each channel has adjustable 16-bits (65536 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 functioning, and built-in LED open detection circuit to detect error status.
