Working Principles

The TC4426VPA operates by receiving an input control signal (IN) that determines the state of the gate driver outputs (LO and HO). When the input signal is high, the LO output is driven low, while the HO output is driven high. Conversely, when the input signal is low, the LO output is driven high, and the HO output is driven low. This differential output configuration allows efficient driving of N-channel enhancement mode MOSFETs.
