Working Principles

The TC4422CPA is a high-speed, high-current driver IC designed to efficiently drive MOSFETs and IGBTs. It operates by receiving an input control signal (IN) and generating corresponding high-side (HO) and low-side (LO) output signals to drive the gate of the power device. The bootstrap supply voltage (VBB) is used to provide the necessary voltage for the high-side gate drive.

When the input control signal is received, the TC4422CPA quickly switches the output signals, enabling fast transitions of the power device. The short propagation delay ensures precise timing and reliable switching performance. Additionally, the shutdown input (SD) allows for power saving by disabling the driver when not in use.
