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 ...

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 ...

Through simple circuit modifications, designers can use peak current limiting to produce a constant current source. Fault protection is a critical function of all power supply controllers. Nearly all ...

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 ...

Not that this happens often, but what do you do when faced with a repair where you don’t know the power source but you do know you have to drive LED backlighting? When faced with this dilemma [Eric ...

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 ...

Bulletin 140G molded-case circuit breakers react up to three times faster to minimize downtime Industrial automation customers can improve their short-circuit protection with a new line of ...

Designed and dual-rated for AC and DC applications, the Eaton FAZ-NA and FAZ-NA-L series current-limiting miniature circuit breakers from AutomationDirect offer protection for application with up to ...

Central Semiconductor has created a line novel of zero temperature coefficient current limiting diodes, packaged in DPAK and rated at between 27 and 575mA. Minimum voltages range across 1.5 to 2V – ...

Littelfuse claims that its CPC1561B Solid State Relay (SSR) is the highest current (1 A, 60 V) normally-open SSR currently available on the market to integrate both current limiting and thermal ...
