Precision, High-Side Current-Sense Amplifiers The MAX471/MAX472 are complete, bidirectional, high-side current-sense amplifiers for portable PCs, telephones, and other systems where battery/DC power-line monitoring is critical. High-side power-line monitoring is especially useful in battery-powered systems, since it does not interfere with the ground paths of the battery chargers or monitors often found in "smart" batteries. The MAX471 has an internal 35mΩ current-sense resistor and measures battery currents up to ±3A. For applications requiring higher current or increased flexibility, the MAX472 functions with external sense and gain-setting resistors. Both devices have a current output that can be converted to a ground-referred voltage with a single resistor, allowing a wide range of battery voltages and currents.
“Arduino based digital supply See my last poroject on this link about another attempt that I had on digital power suplly. In that case, the TFT display made everything very slow so I had to use another type of display …
“Welcome back. Today we will build a power meter using Arduino. We already build the current meter in a past tutorial and also a capacitance and resistance meter and the inductance meter. Check all those tutorials here and learn more …
