High side switch not working

I have simulated this circuit (where the 2N7000 is the 2N7002 in practice, which is its SMD counterpart) to control power to a sensor with a STM32 board (3.3 V logic). The problem is that it never turns off when I mounted it in my PCB (i.e. the PMOS never turns off). I have tried […]
