IR21365S — 3-Phase IGBT/MOSFET Gate Driver IC with Overcurrent Protection (SOP-28)
The IR21365S is an advanced 3-phase gate driver IC from Infineon (formerly International Rectifier), designed to drive all six switches of a 3-phase inverter bridge using N-channel IGBTs or MOSFETs. It includes integrated overcurrent protection (OCP) via desaturation detection, shoot-through interlock, and fault reporting — making it the preferred solution for protected 3-phase motor drives, solar inverters, and industrial power converters in Pakistan.
