Dallas Semiconductor's standalone, open-circuit-voltage (OCV) based fuel gauge, the DS2786, estimates the available capacity of rechargeable Li+ batteries using a combination of an OCV battery model and coulomb counting. The OCV model measures cell voltage in the open-circuit state and determines battery capacity based on a lookup table stored in the IC. This makes accurate capacity information available immediately after a battery pack is connected, eliminating a 'learn cycle'. During periods of moderate to high discharge rates, which preclude OCV measurements, the DS2786 uses coulomb counting as a secondary means of estimating relative capacity. Using this combination of OCV data and coulomb count, it is able to determine pack capacity simply from a partial charge or discharge cycle. This eliminates the need for a full charge or discharge cycle as required by many fuel-gauge ICs. The DS2786's 12-bit voltage measurement is highly accurate to within ±10 mV (resolution 1,22 mV). The OCV lookup table and other user parameters are stored in 32 bytes of on-chip EEPROM. All data is accessed through an I2C interface. It comes in a 3 x 3 mm, 10-pin TDFN package.
