System trade-offs for high- and low-side current measurements
https://e2e.ti.com/blogs_/b/analogwire/archive/2017/06/01/system-trade-offs-for-high-and-low-side-current-measurementsIn general, there are two ways to measure current. The first is by measuring the magnetic field density generated around a current-carrying conductor. This method is suitable when you require noninvasive current measurements, but you’ll need to justify its relative high cost and complex implementation. The second is to use a small shunt resistance and measure the differential voltage across it that results from the current flow, a direct implementation of Ohm’s law. This method is common due to its high accuracy and low implementation costs. Figure 1 shows the two different methods and underlying physics behind each.
A current-sensing location varies depending on the application and intended use of the measured current. Low-side sensing is preferable for cost-sensitive applications that can tolerate ground disturbances and load shorts. High-side sensing is preferable when ground disturbances cannot be tolerated and load-short detection is required. Traditional discrete implementations compared to dedicated current sensors tend to have limited accuracy, a bigger solution footprint and a relatively higher cost for the same accuracy level.High-side sensing addresses the issues of load short detection and the need to eliminate ground disturbance. The main challenge is the high common-mode voltage that the amplifier needs to tolerate. This challenge, in addition to the accuracy challenges of discrete implementations and cost trade-offs, pushes design engineers to consider other solutions.
