How it works

3 stages · Explore one step at a time

Step 1 / 3

Charge the gate

The driver supplies current through the gate resistor during transitions.

Step 2 / 3

Create the channel

Sufficient positive gate-to-source voltage enables the drain-source current path.

Step 3 / 3

Turn off deliberately

The driver removes gate charge; the pull-down defines the off state when the driver is inactive.
