Gate charge total
WebIn reality the gate charge curve represents a superposition of two cap acitors which are not in parallel, have different values, and carry different voltag es. In the literature, the … WebIt takes a certain amount of time to fully charge a capacitor. The same is true of the capacitance of a MOSFET gate. The most useful specification on a MOSFET datasheet for this is the “Total Gate Charge.” “Injecting” this amount of charge into the gate of a MOSFET fully turns it on.
