As power-supply technology advances, so does the need for accurate current-sense methods. For low- and medium-power applications, low-value current-sense resistors are used almost exclusively. In ...

As EDN's Design Ideas editor, I see a range of design submissions, from good, to not so good. A recent DI I turned down for several reasons included a high-side current sense circuit with ...

One of the standard methods used to measure load current is to insert a low-value resistor in the load line and sense the voltage across it, Figure 1, followed by an analog or digital implementation ...

Vishay has created a 5W 1206 current sense resistor range. Called WSLF1206, it is available in values down to 300μΩ. Only the 300μΩ and 500μΩ versions are rated at 5W, and that is only up to 70°C ...

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 ...
