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
