Working Principles

The TC4425EMF713 is designed to drive MOSFETs and IGBTs in power electronics circuits. It operates by receiving an input control signal (IN) and generating complementary output signals (LO and HO) to drive the low-side and high-side switches, respectively. The bootstrap capacitor (connected to COM and VS pins) provides the necessary voltage for driving the high-side switch.

When the input control signal transitions from low to high, the driver quickly turns on the low-side switch while keeping the high-side switch off. Conversely, when the input control signal transitions from high to low, the driver turns off the low-side switch and turns on the high-side switch. This switching action allows efficient control of capacitive loads in power electronics applications.
