Key Definitions Used on How to Design Over Temperature Protection Circuit

## What are the Common Uses of a P-Channel MOSFET

P-Channel MOSFET is not popularly known compared to the N-Channel variant. Others said it is because difficult to deal with while others are saying it is not supply abundant and there are others saying that it is only limited to few applications. In this article, I will concentrate to the last reason, about applications. So, stay with me as I

## How to Calculate MOSFET Power Dissipation

MOSFET power dissipation is the sum of the conduction loss and the switching losses. These power losses are very different from each other. Conduction loss is the static loss wherein the main contributor is the drain to source on-state resistance of the MOSFET as well as the drain current. While switching losses are dynamic losses that are dependent on the

## How to Compute MOSFET Conduction Loss

MOSFET could be used as a switch or amplifier. Regardless of the application, there is a conduction loss. Let’s explore what is the meaning of conduction loss and how to compute MOSFET conduction loss. Conduction loss is the main contributor to MOSFET power dissipation when operating in a non-switching application. Even in switching applications, conduction loss is still very significant

## How to Get MOSFET Correct RDSon Value

How to get MOSFET correct RDSon value is the pre-requisite to compute the MOSFET conduction loss or static power dissipation. RDSon is the drain to source on-state resistance of the MOSFET. The term “correct” is relative to the target result. Supposing the target is to compute the maximum power dissipation, then the correct RDSon value must be the worst-case value.

## How to Compute MOSFET Switching Losses

There are two types of losses in MOSFET. One is conduction loss and the other one is switching loss. Conduction loss is explained in detail here. Switching loss is not as easy as computing the conduction loss. There are many parameters to consider. You need to understand these parameters to select the correct values.  However, you don’t need any more
