Introduction :
-
The MAX471 sensor can measure either current or voltage. It has wide applications specially for battery sensing for portable PCs, smart phones 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 can measures battery currents up to ±3A.
