Working Principles

The TC4422EPA is a high-speed MOSFET and IGBT driver IC. It operates by receiving a logic input control signal (IN) and generating complementary gate drive signals (LO and HO) for the low-side and high-side MOSFETs or IGBTs, respectively. The bootstrap supply voltage (VCC) provides the necessary gate drive voltage for the high-side driver. The driver's internal circuitry ensures precise timing control, fast switching, and protection against fault conditions.
