dm11c 8位具有短断点侦测及温度保护驱动芯片
dm11c 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 all 8 channels is adjustable by a single external resistor. its built-in openshort 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.
applications indooroutdoor led video display led variable message signs (vms) system package types pdip16, ssop16, sop16, sop16 (with exposed pad), or tssop16 (with exposed pad) 8-bit constant current led driver with error detection
