Most AC-DC power supplies and DC-DC converters have internal current-limiting circuits to protect the power device, and to some degree its load. The majority of over-current-protections include an ...

From traditional fuses to eFuses, understanding the advantages, limitations, and use cases of each technology helps engineers ...

The circuit design was intended to create an adjustable power supply over a range of 1.3V to 12.2V at 1A and be able to provide protection for over-current by utilizing LM723 regulator. LM723 – a ...

Switch-mode power supplies (SMPS) continue to replace linear-regulator types in a host of applications. As the need for more efficient electronics accelerates and as a result of their size, weight, ...

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 ...

Overcurrent protection of conductors is an idea so simple that it is almost self-evident. Excessive current in a conductor results in rapid temperature rise, which damages insulation and creates ...

Note: This article is based on the 2011 NEC. Overcurrent exists when current exceeds the rating of equipment or the ampacity of a conductor. This can be due to an overload, short circuit, or ground ...

When overloads and short circuits occur, there’s always a tradeoff between the power supply shutting down the entire 24 VDC supply and keeping load circuits that aren’t impacted by the failure ...

Toshiba releases a CMOS dual comparator with a high-speed response and a full I/O range for use in overcurrent detection in ...

Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...
