Working Principles

The TC4424AVPA operates by receiving an input signal at the IN pin, which controls the gate voltage of the MOSFET. When the input signal is high, the IC drives the MOSFET's gate voltage high, turning it on. Conversely, when the input signal is low, the IC drives the MOSFET's gate voltage low, turning it off. This allows precise control over the MOSFET's switching behavior.
