nilclass, 1 year ago Could you do similar to diagram 2, but instead of an N-FET use a P-FET between the battery and first resistor in the potential divider? That’s a great idea! Unfortunately I don’t have a P-FET lying around, so cannot try it right now. Or use a zener/TVS diode instead of second resistor to clamp the voltage instead of dividing (more robust). Not sure I understand this point. Which resistor would you replace with a diode?
