DM117 Datasheet PDF

SiTi DM117

DM117 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 8 channels is adjustable by a single external resistor.

GENERAL DESCRIPTION

Its built-in open/short detection and thermal alarm circuits help users detect LED failures and overheating. There are two methods to communicate the error messages to the system. One is through serial output data to indicate which channel has failure. The other is by means of dedicated Alarm pin.

FEATURES

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 real-time 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
