Available integrated circuits can let you program a current limit, but they generally involve microcontrollers or data converters (or both). As an alternative, the circuit of Figure 1 lets you program ...

Ordinary power supply design includes current limiting as a protection feature. In product design, this is usually sufficient in that the engineer decides the loads on the supply by design. However, ...

Download this article in PDF format. It’s now common to see circuit boards that carry hundreds of amps, especially in intensive data-processing applications, electric vehicles, and ac distribution.

Startup surges can damage power systems. These inrush current limiters help control spikes, protect equipment, & save energy ...

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 ...

A previous current limiter works well at low supply voltages but lacks precision at supply voltages above 10 V. This improved version reacts quickly to protect the circuit from drops in load ...
