Comment Post #284626 I'm sorry as I meant no disrespect, the two LEDs are just symbolic, I didn't want to clutter the question with a bigger picture, in total there are 10 LEDs split into two parallel branches and 1ohm current limiting resistors. I only took the part of the schematic I thought relevant. 1,2. based on ...

Question MOSFET not turning completely off
Hello everyone, I have a simple circuit in which I control some LEDs via an MCU and DMG2302UK ( N-channel MOSFET ) Circuit schematic The EN pin is connected to an MCU gpio pin that works at 3.3V. The circuit worked perfectly for some time, and suddenly the LED were always-on (very dim), ...
