Tel:886-3-5645656 Fax:886-3-5645626 DM13C 16-bit Constant Current LED Driver with Error Detection DM13C General Description 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 all 16 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. Features  Constant-current outputs: 5mA to 90mA adjustable by one external resistor  Maximum output voltage: 17V  Maximum clock frequency: 25MHz  Built-in real-time LED open/short detection  Fast detecting response: 0.1us (min.)  Over temperature protection: thermal shutdown (junction temperature > 180°C)  Package and pin assignment compatible to conventional LED drivers (ST2221C, DM134/5/6)  Power supply voltage: 3.3V to 5.5V  Bit-to-bit skew : ±3% @ 25mA~90mA Chip-to-chip skew : ±6% @ 25mA~90mA ±6% @ 5mA~25mA ±10% @ 5mA~25mA Applications  Indoor/Outdoor LED Video Display  LED Variable Message Signs (VMS) System Package Types  DIP24, SOP24, SOP24B, SSOP24, TSSOP24 (with exposed pad), QFN32 (with exposed pad) 16-bit Constant Current LED Driver with Error Detection Version:A.006 、、, Unauthorized reproduction, duplication, use or disclosure of this document will be deemed as infringement.
