What it calculates
The “MOSFET Gate Drive” calculator computes Peak gate current in A from 4 parameters: gate charge qg (nC), switching time (ns), driver voltage (V), pwm frequency (kHz).
A standard physics formula used in educational and engineering tasks.
Example calculation
With parameters Gate charge Qg = 50 nC, Switching time = 50 ns, Driver voltage = 12 V, PWM frequency = 100 kHz the result is 1 A.
