The MAX471 module (HCSENS0041) is a complete, bidirectional, highside current-sense amplifier 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. The module has a built-in 2K Ohm sens resitor giving the module a full sensor range of +/- 3A. An open-collector SIGN output indicates current-flow direction, so the user can monitor whether a battery is being charged or discharged. Operation is from 3V to 36V, and draws less than 100µA over temperature
The module is also supplied with optional 2 way screw terminal and 0.1" pitch header (requires soldering).
