Calibration is not required or possible on the bq77PL900 in stand-alone mode.
The user programs the desired protection settings into the device EEPROM.
The bq77PL900 will then perform according to the datasheet limits on those settings.
Variations within the datasheet limits and other application conditions
such as sense resistor tolerance must be planned for in the system design
and can not be compensated for by a `calibration` of the bq77PL900.
