• Manufacturer: SITI [Silicon Touch Technology Inc.]

DM11C
General Description
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. 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.
