The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...

The IR25750LPBF is a current sensing integrated circuit designed for MOSFET, DirectFET and IGBT current sensing. It has integrated ESD protections and eliminates external current sensing resistors.The ...

Although there are several ways to sense current flowing from a source such as a battery, or to a load such as a motor, the current-sense resistor is among the most widely used approaches. There are ...

Sponsored by Texas Instruments: Current-sensing solutions, buoyed by components like Hall-effect sensors, can offer the monitoring reliability and accuracy needed for applications ranging from EVs to ...

Current sensing remains a challenge and while most engineers use DCR current sensing it is notoriously inaccurate. So what can be done to improve accuracy? The buck converter is the most common power ...

One of the joys of writing for Hackaday comes in learning new things which even after a long engineering background haven’t yet come your way. So it is with the Rogowski coil, an AC current sensing ...

Like many hackers, [Matthias Wandel] has a penchant for measuring the world around him, and quantifying the goings-on in his home is a bit of a hobby. And so when it came time to sense the current ...
