Sep 19, 2017 · Discussed here are two circuits to perform that function. Below is the LTspice simulation of a simple ideal-diode MOSFET circuit using all transistors. The components are inexpensive, …

Dec 15, 2025 · I am using a P-channel MOSFET (SUD50P06-15L-E3 / SUD50P06-15-GnE3) as a high-side electronic switch in a 12–14 V automotive electrical system to control auxiliary lighting.

Mar 17, 2015 · For single MOSFET circuits driving an inductive load, the body-diode will NOT work as a replacement for a flyback diode as it conducts in the wrong direction. Consider for example an N …

Conventional current flows from Drain to Source in an N Channel MOSFET. The arrow shows body diode direction in a MOSFET with a parasitic diode between source and drain via the substrate.

6 Your equations are approximations to the capacitance seen between G-D and G-S of a mosfet in different regions of operation and they are derived based on the physical characteristics of the …

Sep 1, 2024 · That driver can be a small relay, a low-side BJT or mosfet driver, etc. It just needs to hard-switch, our circuit will take care of switching from the 12V supply to the hold supply.

About designing AND gate using N-type mosfets: first image is used everywhere. However, it uses an additional inverter part. Is it not possible to design the circuit like below (second image)? If ...

Mar 18, 2023 · The bootstrap circuit is needed when you use an N-channel MOSFET as a high-side switch. That's because the MOSFET is operating as a source follower (common drain), which means …

Dec 4, 2017 · Questions: 1) How to calculate the MOSFET input resistor? 2) What are the factors affecting the MOSFET input resistor calculation? 3) What will be the maximum, minimum resistor …

Jun 10, 2022 · Note that reverse polarity (reverse voltage at the inputs driving current backwards) is different than load dumping (the load producing a voltage higher than the input driving current …
