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 .
z Constant-current outputs: 5mA to 90mA adjustable by one external resistor z 16-bit linear PWM control current outputs for each channel z Maximum output voltage: 17V z Maximum clock frequency: 25MHz z Selectable internal/external PWM reference clock z PWM free-running capability (refresh rate (~ 275Hz) with internal oscillator (~ 18 MHz)) z Build-in real-time open detection z Package and pin assignment (except QFN32) compatible to pure LED driver series (ST2221C, DM134/5/6, DM13C) z Power supply voltage: 3.3V to 5.5V Applications z Indoor/Outdoor LED Video Display z LED Variable Message Sign.
