MOSFET Gate Driver is a specialized circuit that is used to drive the gate of power MOSFETs effectively and efficiently in high-speed switching applications. The addition of high MOSFET Gate drivers are the last step of the turn-on is to fully enhance the conducting channel of the MOSFET technology.
MOSFET Technology
The Gate Driver works under the same principle as the MOSFET transistor. The Gate Driver provides an output current that provides a charge to the semiconductor by a control electrode. The Gate Driver is also simple to drive and has resistive nature for power uses.
