GENERAL DESCRIPTION
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.) z Over temperature protection: Alarm (junction temperature > 130°C) Shutdown (junction temperature > 170°C) z Sleep mode (sleep current : <5uA) z In-rush current control z Schmitt trigger input z Power supply voltage: 3.0V to 5.5V z Package pin assignment compatible to conventional LED drivers (DM114B...
