[Outline]
The MM8013 is a high accuracy fuel gauge IC for 1-cell Li-ion battery or Li-polymer battery.
The MM8013 measures temperature, voltage and current by high-precision delta-sigma AD converter and executes current integration both at discharging and charging using specifi c battery characteristics parameter and the measurement values.
The MM8013 offers excellent management ability for battery power.
The MM8013 achieves safety and security by following functions: battery degradation detection using capacitance change, anomaly detection.


[Features]

1) High accuracy battery power management

Battery power is based on current integration value which is measured periodically and is controlled
 to minimize its error by correction using open voltage (OCV) and battery characteristics parameter.

2) High precision voltage measurement

Electric current and voltage value are measured by high accuracy 16bit delta-sigma AD converter.
The current resolution is 1mA and the voltage resolution is 1mV.

3) Battery degradation detection

Total capacity of battery is measured periodically and capacitance change status is monitored.
 Degradation detection is done using the depth of capacitance change.

4) Low Current Consumption

Current consumption 60µA (operation)
   20µA (Low Power Active)
   1µA (Shutdown mode)

5) Correspondence interfaceI2C interface

6) Traceability

Battery ID and manufacture / shipment information are stored in nonvolatile
 memory and are accessible.

7) Operating Ambient temperature-20℃ to +85℃

8) Operating voltage2.5V to 5.5V
