The MOSFET does not turn off by a turn-off signal. How do I solve this problem?

MOSFET Gate Drive Circuit

We will explain the case of N-ch MOSFETs.
Confirm whether the control signal voltage Vdrive is close to the GND or not.
When the voltage is not close to the GND, the output impedance of the gate drive circuit may be high. Consider lowering output impedance.
Confirm whether the gate-source voltage VGS is the same as the control signal or not. If it is not, insert a pull-down resistor Rpull between gate and source to ensure the gate-source voltage VGS to the GND level.
Please select Rpull that does not affect the gate driving performance.
