Digital Hall sensor only connects to ground when active
I want to make a power control circuit that turns off when a digital hall sensor detects a magnet.
All digital hall sensors I have found connect to ground when active. I was thinking about using a ...

How can I measure switching power losses in a MOSFET accurately?
I am going to measure under scope the switching power losses in the MOSFETs of my micro power inverter. In any case, the handling load current doesn't exceed 1 A at 24/48 Vrms.
Firstly, I've thought ...

Why do I need I large resistor to the GATE of my MOSFET?
I tried to control the brightness of a LED using a Linear Hall Effect Sensor fed to an Arduino, and PWM output to the gate of a MOSFET connected to a 12V battery.
The LED was flickering a lot, and ...
