MOSFET Driving problem
Power Supplies, in general, have a big capacitor to filter the spikes that comes from it's switching circuitry, which FG does not have. The FG internally will act like a &quot;push-pull&quot; circuit, that forces the input pin voltage to reach the gnd level. Then, if you are using a uC, make sure you select the GPIO pin to &quot;push-pull&quot; functionality.
