Product Descriptions

DM13C 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 all16 channels is adjustable by a single external resistor. Its built-in open/short detection circuits help users detect LED failures.System retrieve the error  messages  to  indicate  which  channel  has  failure  by  serial  output  data.  The  thermal  shutdown function provides the over temperature protection.
