Working Principles

The TC4428AVUA713 is designed to drive MOSFETs and IGBTs efficiently. It operates by receiving an input control signal (IN) and generating corresponding high and low-side output signals (HO and LO). These output signals are used to control the gate voltage of the power devices, enabling efficient switching.

The driver incorporates a bootstrap capacitor (VBS) and a bootstrap supply voltage (VS) pin. This allows for the high-side gate drive voltage to be generated above the VDD supply voltage, ensuring proper operation of the high-side switch.

Additionally, the TC4428AVUA713 includes built-in protection against shoot-through currents, which can occur when both the high and low-side switches are simultaneously turned on. This protection feature helps prevent damage to the driver and power devices.
