Mosfet driver ic circuit. A gate driver is a type of power amplifier that accepts a low-power input from a controller IC and produces a high-current drive input for the gate of a high-power transistor such as an Insulated-Gate Bipolar Transistor (IGBT) or power MOSFET. These circuits help ensure efficient switching and enhanced performance in power electronics. Two characteristics are useful to understand the behaviour of any power device. , “Safety Considerations in Power Supply Design” [3] Ernest H. The other terminals of a MOSFET are source and drain, and for an IGBT they are called collector and emitter.
