Description
The open LED protectorprovides a switching electronic shunt path whenan LED in an LED arrayfailsas an opencircuit.This ensures that theentire array of LED s will continue to functioneven if a single LED inthearray does not. This provides higher reliable lighting functions In applications such as headlights, aircrafts, aircraft runway lighting, Roadside warning lights, etc.This device is compatible with one,two and Three watt LEDs that haveanominal 3V forward characteristic. Electrcal Characteristics (Tamb=25℃) General Notes:
- All measurements are made at an ambient temperature of 25℃.Ipp applies to -40℃ through +85℃ temperature range.
- Special voltage(VBO and VDRM) and holding current(IH) requirements are available up on request.
