Overview
19-0335; Rev 2; 12/96 Precision, High-Side Current-Sense Amplifiers _______________General Description The MAX471/MAX472 are complete, bidirectional, highside 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-...
