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.
