PLED6M Series
PLED6M Series
Description
The open LED protector provides a switching electronic
shunt path when an LED in an LED string fails as an
open circuit. This ensures that the entire array of LEDs
will continue to function even if a single LED in the array
does not. This provides higher reliable lighting functions
in applications such as headlights, aircraft lights, airport
runway lighting, roadside warning lights, etc. This device is
designed to be used with one watt LEDs, nominally 350mA
@ 3V, and is available in POWERMITE
®* package (CSP)
which is ideal for dense board applications.
