Tel：886-3-5645656 Fax：886-3-5645626 DM13H-E DM13H-E 16-Channel Constant Current LED Driver With Error Detection General Description DM13H-E is a 16-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. Its built-in LED open/short detection, output channels short to GND detection help users to detect LED failures, outputs short. The thermal alarm and shutdown functions provide the over-temperature protection. Features z 16-Channel Constant-current outputs: 3mA to 90mA adjustable by one external resistor z Maximum output voltage: 17V z Maximum cascade clock frequency: 25MHz 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°C) z In-rush current control z Schmitt trigger input z Power supply voltage: 3.0V to 5.5V z Packa...
