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), ...

What's driving the need for protection devices and the challenges of implementing them. Traditional types of protection devices. Different approaches to protection, including surge stoppers. The ...

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 ...

Although they are one of the fastest-growing segments of today's battery market, lithium-ion batteries are not without disadvantages. Fragile by nature, they require protection circuits in order to ...

The global market for battery-powered applications is rapidly growing, including power tools, service robots, light electric vehicles, and many others. The evolution of switched-mode power supply ...

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 ...

Using a MOSFET as a switch is generally pretty simple. Make the gate voltage sufficient with respect to the source and current flows through the channel. However, if you are switching higher voltages, ...

The gate current is programmable, helping engineers minimize MOSFET switching noise to meet electromagnetic compatibility ...

[Afroman’s] latest video shows you how to add reverse voltage protection with minimal power loss. At some point, one of your electronic concoctions will turn out to be very useful. You want to make ...

Analog Devices, which recently acquired Linear Technology, has launched the LTC7003, a high speed, high side N-channel MOSFET driver that operates up to a 60V supply voltage. Its internal charge pump ...
