General Description

The DM164 is a LED current sink driver incorporating independent shift registers and data latches for grayscale PWM data (GD mode*1) and current adjustment data (D&G mode*1), 8x3-channels constant current circuitry with current value set by 3 external resistors, 65,536 grayscale PWM function unit, 128 levels current adjustment for each channel and 256 levels global brightness control (White balance).

Each channel provides maximum current of 90mA.

The DM164 also supports the LED open detection capability, thermal alarm and shutdown function.

Key Features
