General Description
The DS2786 estimates available capacity for rechargeable Li-Ion and Li-Ion Polymer batteries based on the cell voltage in the open-circuit state following a relaxation period.
The open-circuit voltage (OCV) is used to determine relative cell capacity based on a lookup table stored in the IC.
