It’s not easy being a current-sense resistor: so much is expected of this basic function of determining current flow by simple measurement of voltage across a known resistance, then applying Ohm’s Law ...

Current sensing is used to perform two essential circuit functions. First, it is used to measure “how much” current is flowing in a circuit, which may be used to make decisions about turning off ...

Accurately measuring current flow is a standard requirement in several applications (Fig. 1). Depending on the specific need, the options available to designers can include discrete designs assembled ...
