MOSFET Overload Protection Design Made Easy
The Problem: MOSFET Overload and Burnout When a MOSFET handles more current than it’s rated for, it heats up rapidly and can fail catastrophically. This is a common issue in motor drivers, power supplies, and battery chargers—especially when there’s no built-in overload protection. For hobbyists and prototypers, this often results in damaged components …
SMPS Low-Noise Design Tips: A Beginner’s Guide
The Problem : When designing a Switch Mode Power Supply (SMPS), one common issue is noise interference—unwanted electrical signals that can disrupt the operation of sensitive equipment. This is especially crucial in audio, communication, and precision electronics. The good news is that with the right design adjustments, you can significantly reduce this noise. …
MOSFET Paralleling Design Guide: A Simple Approach for Hobbyists and Engineers
When designing circuits that require high current, one common challenge is managing heat dissipation and ensuring balanced current sharing. Paralleling MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) is a common solution, but it comes with its own set of issues—such as uneven current distribution, leading to overheating or failure of the MOSFETs. The Problem and Solution : …
