WebFeb 2, 2024 · Current is limited when using MOSFET as a switch. I want to realise a basic ESP32 board to control three fans connected in parallel. In order to control the fan power, I'm using the FQP30N06L, a logic-level N-channel MOSFET. As you can see in the simplified schematic below, the MOSFET gate is connected to an ESP32 GPIO pin. WebFeb 1, 2024 · p-channel MOSFET switch. I want to use a MOSFET as a switch driven by my microcomputer. The original circuit using N-channel MOSFET is on the left side. Honestly, I do not understand the choice of …

I added diode D1 as flyback diode given that I figured the water pump to be an inductive load, but I am not sure whether it is connected correctly. fidic claim templateWebMar 27, 2024 · 2. Assuming the 2N2222 is good, and the MCU gnd === the emitter voltage, and assuming the MCU output goes to 0.0 volts, that circuit should work. Lets diagnose a bit. Make the base resistor about 1,000 ohms. That puts a (good) transistor well into saturation when MCU output is near 3.3v. fidic contingencyWebNov 5, 2024 · N channel MOSFETs are best used for low side switches. The load is between Vcc and the drain of the MOSFET. Source to ground. The Rds (on) of the MOSFET is around 2Ω. Kind of on the high side for MOSFETs.

I've found many suggestions online for MOSFETs that are compatible with 3V GPIO but they are all TO220 style MOSFETs which is a bit too large. fidic casesWebWith a 220 resistor, the GPIO current will be about 12mA (3.3V - 0.7 Vbe = 2.6V / 220 = 12mA). This should be plenty of current to push the transistor into saturation, and not so much that it will overload the GPIO. I don't know why you didn't fry the GPIO without the resistor - maybe there is some kind of current limiting on the ESP32 GPIO. fidic certification coursesWebAug 11, 2024 · Switches Tutorial for Arduino, ESP8266 and ESP32.
