QW2882 Datasheet Summary
LED Emergency Lighting driver
General Description
Package Reference
QW2882 is a LED driver designed for Emergency Lighting. The QW2882 employs patent protected main line detecting methodology to control and drive the emergency lighting system, without any peripheral ponents. The QW2882 can drive an LED load directly or to enable a boost circuitry, while the AC input main line could be 85-265Vac.
An AC main line detection filter is integrated in QW2882, to improve the immunity of main line glitch, and to improve the detection of emergency lighting status.
QW2882 can deliver as large as 1.5A output current. QW2882 is available in SOT23-5 package.
