IR2156SPBF Datasheet PDF - Infineon

The IR2156SPBF is a Ballast Control IC incorporates a high voltage half-bridge gate driver with a programmable oscillator and state diagram to form a complete ballast control IC. The IR2156 features include programmable preheat and run frequencies, programmable preheat time, programmable dead-time and programmable overcurrent protection. Comprehensive protection features such as protection from failure of a lamp to strike, filament failures, as well as an automatic restart function, has been included in the design.
