Working Principles

The TC4427EMF is a high-speed driver IC designed to control the switching of MOSFET and IGBT devices. It operates by receiving input signals through the IN pin, which controls the state of the driver. When the input signal is high, the driver outputs a high voltage on the HO pin and a low voltage on the LO pin, enabling the connected device to turn on. Conversely, when the input signal is low, the driver outputs a low voltage on the HO pin and a high voltage on the LO pin, turning off the connected device.
