DIMMING BALLAST CONTROL IC

Data Sheet No. PD60194_A IR21592(S) IR21593(S) Features DIMMING BALLAST CONTROL IC • Full lamp fault protection • Brown-out protection • Automatic restart • Micro-power startup • Zener clamped Vcc • Over-temperature protection • 16-pin DIP and SOIC package types Parameter Deadtime Frequency Range IR21592 1.8us See Graph 11 IR21593 1.0us See Graph 12 • Ballast control and half-bridge driver in one IC • Transformer-less lamp power sensing • Closed-loop lamp power control • Closed-loop preheat current control • Programmable preheat time • Programmable preheat current • Lamp ignition detection • Programmable ignition-to-dim time • 0.5 to 5VDC dimming control input • Min and max lamp power adjustments • Programmable minimum frequency • Internal current sense blanking Description Description: The IR21592/IR21593 are complete dimming ballast controllers and 600V half-bridge drivers all in one IC. The architecture includes phase control for transformer-less lamp power sensing and regulation which minimizes changes needed to adapt non-dimming ballasts for dimming. Externally programmable features such as preheat time and current, ignition-to-dim time, and a complete dimming interface with minimum and maximum settings provide a high degree of flexibility for the ballast design engineer. Protection from failure of a lamp to strike, filament failures, thermal overload, or lamp failure during normal operation, as well as an automatic restart function, have been included in the design..
