The device incorporates shift registers, data latches, and constant current circuitry on the silicon CMOS chip.
The maximum output current of each channel is set by a single external resistor.
Overall output currents can be adjusted by a 7-bit serial shift-in data.
Its built-in LED open/short detection, output channels short to GND detection help users to detect LED failures, outputs short.
The thermal alarm and shutdown functions provide the over-temperature protection.
Features z 8-Channel Constant-current outputs: 5mA to 90mA adjustable by one external resistor z Maximum output voltage: 17V z Maximum cascade clock frequency: 25MHz z 7-bit linear global brightness control z Built-in LED open/short detection: Real-time detection or Smart detection z Built-in Outputs short to GND detection: Real-time or Smart detection z Fast detecting response: 100ns (min.
