Working Principles

The TC4422VPA operates by receiving an input control signal (IN) which determines the state of the driver outputs (LO and HO). When the input is high, the LO output is low and the HO output is high, turning on the low-side MOSFET and turning off the high-side MOSFET. Conversely, when the input is low, the LO output is high and the HO output is low, turning off the low-side MOSFET and turning on the high-side MOSFET. This differential drive configuration ensures efficient switching of power MOSFETs.
