Unidirectional Open LED Protector from Littelfuse Prevents Damage from Reverse Polarity Voltages

2014/02/18Littelfuse  LED

 

The PLEDxUx Unidirectional Series Open LED Protector provides a switching electronic shunt path when one LED in a string fails as an open circuit. PLED devices are connected in parallel with each LED in a series string. If one LED fails as an open circuit, the PLED connected to it turns on and carries the current that would have gone through the failed LED, so the remainder of the string continues to function. LEDs cannot withstand voltages of reverse polarity; the PLEDxUX Series provides reverse battery/power polarity protection for greater LED reliability.


Features:
・Electronic shunt/bypass for open LEDs
・Reverse battery/power protection
・Fast switching
・Small footprint, DO-214AA or QFN package
・Automatically resets after power cycle
・RoHS compliant
