IR21571PBF - FULLY INTEGRATED BALLAST CONTROL IC

Download the IR21571PBF datasheet PDF. This datasheet also covers the IR21571S variant, as both devices belong to the same fully integrated ballast control ic family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key Features

  • Programmable preheat time & frequency.
  • Programmable ignition ramp.
  • Protection from failure-to-strike.
  • Lamp filament sensing & protection.
  • Protection from operation below resonance.
  • Protection from low-line condition.
  • Automatic restart for lamp exchange.
  • Thermal overload protection.
  • Programmable deadtime.
  • Integrated 600V level-shifting gate driver.
  • Internal 15.6V zener clamp diode on VCC.
