Feb 14, 2024 · Discussion on using NMOS and PMOS as current sources, sinks, or voltage sources in circuits, addressing challenges and pin configurations.

Nov 5, 2021 · Hi readers, is this the correct way to power a PMOS mosfet? I am unfamiliar with PMOS but quite familiar with NMOS. Question: How to use PMOS to power a 10 Ohm Load? Thank you I …

Oct 29, 2024 · HI. I am trying to design a CMOS Inverter. NMOS turns on and off as expected. However, PMOS does not fully turn off

Jun 17, 2024 · The PMOS should provide voltage across this load for a very short period of time (100us-150us). During switching, I have observed that the MOSFET works absolutley fine during ON state, …

Jan 11, 2012 · The problem I'm having is trying to get the pmos to act as a switch and connect the two resistors. The gate is connected to a microcontroller logic pin with a +5v high output. 3.7 volts is on a …

Jun 8, 2025 · Hi, I am working on a PMOS-based reverse polarity protection circuit for a lithium thionyl chloride cell, and I have a few doubts about the necessity and sizing of certain components — …

Jun 7, 2023 · The PMOS MOSFET chosen is about as good as it gets for PMOS esp in a TO-220 case. There are some better ones (sub 10mOhm) in a SMT DPAK or similar case but heatsinking those is …
