Gate Driver Design Calculator

Design MOSFET gate drive circuits. Calculate drive current, power, and gate resistor values.

MOSFET Q_g Total (nC)

Gate Voltage V_gs (V)

Switching Frequency (kHz)

Gate Resistance R_g (Ω)

Driver Supply (V)

Rise Time Target (ns)

Avg Current: I_{g_avg} = Q_g×f_sw

Peak Current: I_{g_peak} = V_gs/R_g

Power: P_drive = Q_g×V_dd×f_sw
