Product Descriptions

DM13H 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.  Overall  output  currents  can  be  adjusted  by  a  7-bit  serial  shift-in  data. 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.
