Working Principles

The TC4421ESM is a high-speed driver IC designed to efficiently drive MOSFETs and IGBTs. It operates by receiving an input signal at the IN pin, which controls the state of the driver. When the input signal is high, the high-side output (HO) is driven high, while the low-side output (LO) is driven low. Conversely, when the input signal is low, HO is driven low and LO is driven high.

The TC4421ESM's fast rise and fall times, along with its low propagation delay, ensure quick and accurate switching of power transistors. This allows for efficient control of various power applications, such as motor drives, power supplies, and inverters.
