General Description

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.

Key Features

  • z Constant-current outputs: 5mA to 60mA adjustable by one external resistor z 12-bit linear PWM control current outputs for each channel z Maximum output voltage: 17V z Maximum clock frequency: 25MHz z Auto-Reload / One-Shot Mode selection. z Serial out clock edge selection.
  • Rising / Falling edge selection z Internal / External PWM clock mode selection z Built-in real-time open detection z Package and pin assignment compatible to conventional LED drivers (DM134/5/6, DM13C) z Power suppl.
