Description
The IR21571 is a fully integrated, fully protected 600V ballast control IC
designed to drive virtually all types of rapid start fluorescent lamp
ballasts. Externally programmable features such as preheat time & frequency,
ignition ramp characteris tics, and running mode operating frequency provide a
high degree of flexibility for the ballast design engineer. Comprehensive
protection features such as protection from failure of a lamp to strike,
filament failures, low dc bus conditions, thermal
overload, or lamp failure during normal operation, as well as an automatic
restart function, have been included in the design. The heart of this control
IC is a variable frequency oscillator with externally programmable deadtime.
Precise control of a 50% duty cycle is accomplished using a T-flip-flop. The
IR21571 is available in both 16 pin DIP and 16 pin narrow body SOIC packages.
