Working Principles

The TC4429COA operates by receiving an input signal at the IN pin, which controls the driver's behavior. When the input signal is high, the driver activates the high-side gate driver output (HO) and low-side gate driver output (LO), allowing current to flow through the connected MOSFET. Conversely, when the input signal is low, both outputs are turned off, preventing current flow.

The driver utilizes internal circuitry to provide the necessary voltage levels and current capabilities to drive the MOSFET efficiently. By controlling the timing and duration of the input signal, precise switching of the MOSFET can be achieved.
