Current-sense amplifiers MAX471/472
The MAX471/472 are complete, bidirectional, high-side current-sense amplifiers for portable PCs, telephones, and other systems where battery /d.c. power-line monitoring is required. High-side power-Iine 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.
