The FAN7532 provides simple and high performance electronic ballast control functions. Optimized for an electronic ballast, the FAN7532 requires a minimum board area, and reduces component counts. The FAN7532 is intended to drive two power MOSFETs in the classical half-bridge topology with all the features needed to properly drive and control a fluorescent lamp. The FAN7532 has many comprehensive protection features that work through filament failure, failure of a lamp to strike, and automatic restarts. A dedicated timing section in the FAN7532 allows the user to set the necessary parameters to preheat, ignite, and run the lamp properly.
