I built this simple MOSFET driver and it won't work.
The MOSFET used is AOD442. Supply+ is 24V. The load is a vacuum pump. The control signal is from a Raspberry Pi 4B. I took a few measurements and when I turn on the control signal I can see 12V on the gate pin as expected. However, the pump does not turn on. I connected the pump across the supply separately just to check if it works and it does. Completely stumped! Why won't this work?
SUPPLY+
andOUT
, yes? \$\endgroup\$MOUT
andGNDPWR
instead ofSUPPLY+
andMOUT
. It works now. \$\endgroup\$
