QW2880A Datasheet Summary
LED Emergency Lighting driver
General Description
Package Reference
QW2880A is a LED driver designed for Emergency Lighting., The QW2880A employs patent protected main line detecting methodology to control and drive the emergency lighting system, without any peripheral ponents. The QW2880A can drive an LED load directly or to enable a boost circuitry, while the AC input main line could be 85-265Vac.
QW2880A integrates a precise single lithium-ion /polymer battery management functional blocks to protect the lithium-ion/polymer battery, including Over Current Protection, Over Charge Protection, Over Discharge Protection and Short Circuit Protection.
QW2880A can deliver as large as 2A output current. QW2880A is available in SOP-8 package.
