If you have an application in which a MOSFET is already used to switch a load, it is relatively easy to add short-circuit or overload protection. Here we make use of the internal resistance RDS(ON), ...

For the PDF version of this article, click here. Protecting power transistors against overcurrent failure has always been a challenging issue in power circuit design. In order to protect against even ...

In this circuit, a MOSFET protects a reverse-connected battery from excessive current. The MOSFET conducts only when the battery is correctly connected, which lets the battery charge or discharge. In ...

The need to improve reliability while reducing product cost has seen a proliferation of self-protected MOSFETs in the automotive sector. At the same time, consumer demand for more 'feature rich' ...

Understanding the advantages, limitations, and use cases of each technology helps engineers create reliable consumer products.

Linear Technology has introduced the LTC4380, an ultralow quiescent current (IQ) surge stopper, providing compact overvoltage and overcurrent protection. Linear Technology has introduced the LTC4380, ...
