The DS2755 Li+/NiMH battery fuel-gauge IC is designed to monitor single-cell Lithium-ion (Li+) or 3-cell NiMH battery packs. With the appropriate circuit modifications, however, the DS2755 can also be used to monitor a 2-cell Li+ battery pack. This application note describes such a reference circuit, which allows the DS2755 to monitor the voltage, current, remaining capacity, and temperature of a multiple-cell pack. Crucial circuit components are discussed in detail, including configuration issues for the DS2755 itself.
