Description
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.
