The "Circuit Shorts" series continues! This time, Saar covers dual-BJT constant current. There are many ways of driving LEDs and each has its merits for a particular application. Using a current ...

This circuit uses a few standard discrete components to provide a user-settable current-limit function with closed-loop performance. In addition, the limiter function can be turned on and off via an ...

A doubly fed induction generator (DFIG) configured for crowbar protection faces the following problems during low voltage ride through (LVRT): delayed input of crowbar protection and the difficulty in ...

FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...

Hot-swap circuits are among those measures put in place to protect equipment or personnel, or both. Some power supplies, for example, have built-in and adjustable current limiting (standard in ...

Abstract: A new intelligent IGBT for auto motive ignition system with a precise and stable constant current limiting circuit has been shown to operate at a constant current of 11±1.0 A between –40°C ...

Constant current limiting circuits are commonplace, but sometimes a constant power limiting function is desired instead. This can be because downstream loads, like DC/DC converters, present a constant ...

Abstract: This article presents a current-limiting protection circuit, which is being used in the design of USB power management chip. Compared with the traditional current-limiting protection circuit ...
