IR2125S屬于集成電路（IC）的柵極驅動器。由英飛凌科技股份公司制造生產的IR2125S柵極驅動器柵極驅動器電源管理集成電路 (PMIC) 可用于提供隔離、放大、參考位移、自舉或其他必要功能，這些功能可將來自電源轉換應用中控制設備的信號連接到電源被控制通過的半導體設備（通常為 FET 或 IGBT）。任何特定設備提供的確切功能各不相同，但與它適合驅動的半導體配置相關。

描述 Description

The IR2125(S) is a high voltage, high speed power MOSFET and IGBT driver with over-current limiting protection circuitry. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. Logic inputs are compatible with standard CMOS or LSTTL outputs, down to 2.5V logic. The output driver features a high pulse current buffer stage designed for minimum driver cross-conduction. The protection circuitry detects over-current in the driven power transistor and limits the gate drive voltage. Cycle by cycle shutdown is programmed by an external capacitor which directly controls the time interval between detection of the over-current limiting conditions and latched shutdown. The floating channel can be used to drive an N-channel power MOSFET or IGBT in the high or low side configuration which operates up to 500 volts.
