Sensing current on the high side
https://www.electronics-lab.com/home-community-blogs-benchtalk-sensing-current-high-side/
Michael Dunn@ edn.com discuss about current sense on the high side of power source. At their heart, the majority of DC current sense circuits start with a resistance in a supply line (though magnetic field sensing is a good alternative, especially in higher-current scenarios). One simply measures the voltage drop across the resistor and scales […]
