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 A...
