MM3324 has characteristics to monitor battery temperature, charge current and charge voltage.
In addition, MM3324 IC has integrated a charge FET and a current sensing resistor which allows lower costs (in conventional charge control ICs, these are external devices)
The reverse current protection function is also added.
The MinebeaMitsumi lithium battery management circuits are made in Japan and are of the highest quality. They will be perfectly suited for your applications.
