Mosfet usage and P- vs N-channel
This turns the MOSFET ON and current will flow through the load. N CHANNEL MOSFET. (Load connected between Drain and +12V) When the PIC output is LOW, the transistor is OFF and the gate of the N MOSFET is HIGH (12V). This means the N MOSFET is ON and current will flow through the load.

2023年8月1日 · The n-channel power mosfet : SiS176LDN and a power supply (from mean well) : which outputs 20V and 3A. Based on the answers below that talk about this working, this should switch on and off with just a 3.3v gate since Vgs is within the range that this should conduct and turn off since the gate is pulled to ground.
Can we use an n-channel MOSFET instead of a p-channel?
2020年10月26日 · The problem with an n-channel MOSFET is that the gate needs to be a threshold voltage (Vt) above the terminals in order to turn on. So, your solar panel puts 12V on the source and your battery leaves 12V on the drain and your gate is a maximum of 12V.
Why N-channel MOSFETs are better than P-channel MOSFETs?
Why n-channel MOSFTs are better then p-channel MOSFETs? The only real reason is that electron mobility is higher than hole mobility. All of the physical advantages fall out of that (gate-capacitance, channel resistance, cost, size, thermal rating, etc) Every other difference is just a difference. Let's consider polarity.
transistors - Switching DC with MOSFET: p-Channel or n-Channel; …
An N-channel high-side switch (Topology #1) has better performance than a comparably sized/priced P-channel high-side switch, but the gate drive is more complicated, and has to be relative to the N-channel MOSFET source terminal, which varies as the circuit switches, but there are specialized gate drive ICs which are meant to drive high-side N ...

2013年5月14日 · Even the discussion it is taken from has people expressing uncertainty re arrow direction. As shown IF that is an N Channel then it is implying body diode polarity and NOT current flow in source. Thusly _____' Circuit Lab is apparently the (or a) culprit. This is their symbol for an N Channel MOSFET. A nasty piece of work, alas.
