When tasked with a current sensing requirement, designers typically look first to using dedicated resistors designed for this task. Occasionally though there is the temptation to consider sensing ...

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 ...

In-circuit testers rely on bed-of-nails-type fixtures that give the tester access to every node (or net) of the printed circuit board (PCB). Using this access, the tester takes a divide-and-conquer ...

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 ...

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 ...

MANCHESTER, N.H., July 08, 2024 (GLOBE NEWSWIRE) -- Allegro MicroSystems, Inc. (“Allegro”) (Nasdaq: ALGM), a global leader in power and sensing solutions for motion control and energy-efficient ...

What qualities are needed for current sensors in an automotive environment? Warren Pettigrew spells out the requirements. Today what is expected of automotive sensors is quite different to what was ...

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 ...
