Description
The IR2156 incorporates a high voltage halfbridge gate driver with a programmable oscillator and state diagram to form a plete ballast control IC. The IR2156 features include programmable preheat and run frequencies, programmable preheat time, programmable dead-time, and programmable overcurrent protection. prehensive protection features such as protection from failure of a lamp to strike, filament failures, as well as an automatic restart function, have been included in the design.
