Description
The MAX17043 IC, from Maxim Integrated, is designed to monitor lithium-ion (Li+) batteries.
Using a sophisticated Li+ battery-modeling scheme, called ModelGauge™, it can track the battery’s SoC (State of Charge) without the need for battery relearn cycles and an external current-sense resistor.
You can get actual voltage and SoC values via an I2C interface.
You can also set an alarm threshold for low-battery warning: if the remaining charge goes under that threshold, the ALRT PIN is set low and the corresponding bit in the CONFIG register is set to 1.
Installation
I wrote a library to use MAX17043 IC with Arduino; you can find it on Github.
– click ZIP button:
– open the downloaded zip file:
– extract it in the libraries subfolder in your Arduino IDE path:
– rename the extracted folder in MAX17043:
