Measuring the voltage drop across a current-sense resistor can be a trivial issue or a challenging one depending on the rail voltage and other factors. The problem with low-side sensing is that it “ungrounds” the load, and the alternative is high-side sensing. This part looks at the use of isolation to deal with CMV […]
