DM13G DM13G 16-bit Constant Current LED Driver With Error Detection General Description DM13G 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. The global current also can be further adjusted by 7-bit serial shift-in data. Its built-in LED open/short detection, output channels short to GND detection and thermal alarm circuits help users detect LED failures, outputs short and overheating. There are two methods to communicate the error messages to the system. One is through serial output data to indicate which channel has failure. The other is by means of dedicated Alarm pin. Features Constant-current outputs: 5mA to 90mA adjustable by one external resistor Maximum output voltage: 17V Maximum clock frequency: 30MHz 7-bit linear global brightness control Built-in LED open/short detection: Real-time detection or Smart detection Outputs short to GND detection: Smart detection Fast detecting response: 100ns (min.) Over temperature protection: Alarm (junction temperature > 130°C) Shutdown (junction temperature > 170°C) Sleep mode selection :sleep current < 5uA (typ.) Ghost image elimination In-rush current control Schmitt trigger input Power supply voltage: 3.0V to 5.5V Applications LED Variable Message Signs (VMS) System Indoor/Outdoor LED Video Display Package SSOP28, TSSOP28E, QFN32 |
