The better the analog front-end for measuring battery current, the more accurately you'll be able to gauge the remaining run-time for your battery-backup system. Here's a discrete front-end design ...

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 ...

How to effectively measure ultra-low bias current by recreating the measurement scheme from an app note. Measuring input capacitance and input current. Creating a better measurement environment. 3. Cp ...

Next is the H-bridge, which resembles an H (Figure 2), which is used typically with a brushed DC motor. In addition to run, coast, and break operating modes, it can also reverse a motor. Simplified ...
