DM11H - 8-Channel Constant Current LED Driver

General Description

DM11H is a 8-channel constant-current sink driver specifically designed for LED display applications.

The device incorporates shift registers, data latches, and constant current circuitry on the silicon CMOS chip.

The maximum output current of each channel is set by a single external resistor.

Key Features

  • z 8-Channel Constant-current outputs: 5mA to 90mA adjustable by one external resistor z Maximum output voltage: 17V z Maximum cascade clock frequency: 25MHz z 7-bit linear global brightness control z Built-in LED open/short detection: Real-time detection or Smart detection z Built-in Outputs short to GND detection: Real-time or Smart detection z Fast detecting response: 100ns (min. ) z Over temperature protection: Alarm (junction temperature > 130°C) Shutdown (junction temperature > 170.
