Using the DS2786 Battery Fuel Gauge in the Host Side of a 2-Cell Battery Application
The DS2786 stand-alone, open-circuit-voltage (OCV) based fuel gauge has an operating range designed for a 1-cell lithium-ion (Li+) battery pack. However, the DS2786 can also be used in a 2-cell application by adding a few extra components to the typical application circuit. This application note details a circuit for using the DS2786 on the host side of a 2-cell Li+ battery pack.
