DS2781
PARAMETER EEPROM
Model data for the cells, as well as application operating parameters are stored in the Parameter EEPROM
memory (block 1, addresses 60h–7Fh). The ACR (MSB and LSB) and AS registers are automatically saved to
EEPROM when the RARC result crosses 4% boundaries. This allows the DS2781 to be located outside the
protection FETs. In this manner, if a protection device is triggered, the DS2781 cannot lose more that 4% of charge
or discharge data.
