DM633 - 16-CHANNEL CONSTANT CURRENT LED DRIVER

General Description

DM633 is a 16-channel constant current sink LED driver.

Each channel has adjustable 12-bits (4096 steps) grayscale PWM control current outputs.

7-bit global brightness control is included in supporting user to adjust chip current easily.

Key Features

  • z Constant-current outputs: 5mA to 90mA z 12-bit PWM control current output per channel z 7-bit high accuracy global brightness control z Maximum output voltage: 17V z Maximum clock frequency: 25MHz z Selectable internal/external PWM reference clock z PWM free-running capability (refresh rate ~ 4.4k Hz with internal oscillator ~ 18 MHz) z Build-in real-time LED open/short detection z Thermal Alarm and Shotdown.
  • Alarm : Junction Temperature >110℃ Shutdown : Junction Temperature > 180℃ z.
