✍ 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).

Tips:
The voltage detection module input voltage not greater than 5Vx5 = 25V (if using 3.3V systems, input voltage not greater than 3.3Vx5 = 16.5V).
AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V / 1023), so the minimum voltage of input voltage detection module is 0.00489 Vx5 = 0.02445V.
