DM137 is a 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 value of all 16 channels is adjustable by a single external resistor.

z Constant-current outputs: 5mA to 90mA adjustable by one external resistor z Maximum output voltage: 17V z Maximum clock frequency: 25MHz z Built-in LED open/short detection: real-time monitor or smart detection modes z Fast detecting response: 0.1us (min. ) z Over temperature protection: Alarm (junction temperature > 110°C) Shutdown (junction temperature > 180°C) z Power supply voltage: 3.3V to 5.5V.
