Description

The IR2156 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, program-

mable dead-time, and programmable over-current pro-

tection. Comprehensive protection features such as

protection from failure of a lamp to strike,filament fail-

ures, as well as an automatic restart function, have

been included in the design. The IR2156 is available in

both 14 lead PDIP and 14 lead SOIC packages.
