The main supply voltage in a notebook computer drops when the wall cube is unplugged, because battery voltage is generally lower than that from a wall cube. Even the voltage of a lithium-ion battery ...

Measuring dynamic current flow has always been an important parameter for managing system performance, and doing so has become even more so with the proliferation of smarter management functions for ...

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 ...

Using a low-value resistor to sense current is a direct application of Ohm’s Law, yet requires understanding of the key parameters and tradeoffs. Although there are several ways to sense current ...

Seeking something-or-other, I came across a high-side current sense circuit that I had never noticed before. Here it is (right), in an app note for the OnSemi NCP3020A buck dc-dc converter controller, ...
