Working Principles

The TC4423CPA is a high-speed, high-current driver IC designed to control the switching of MOSFETs and IGBTs. It operates by receiving a logic input control signal (IN) and generating corresponding high and low-side output signals (HO and LO). These output signals drive the gate of the MOSFET or IGBT, enabling efficient switching between on and off states.

The IC incorporates built-in protection against shoot-through currents, which prevents both the high and low-side outputs from being active simultaneously. This feature ensures safe operation and protects the driver and power devices from damage.
