Alarm Bits
OVER_CHARGED_ALARM bit is set whenever the bq2060A detects that the battery is being charged beyond
the Maximum Overcharge limit. This bit is cleared when the bq2060A detects that the battery is no longer being
charged (i.e., the bq2060A detects discharge activity or no activity for the digital filter timeout periods). The digital
filter timeout period (seconds) equates to 10 times the value shared in Digital Filter EE0x52.
TERMINATE_CHARGE_ALARM bit is set when the bq2060A detects that one or more of the battery charging
parameters are out of range (e.g., its voltage, current, or temperature is too high) or when the bq2060A detects a
primary charge termination. This bit is cleared when the parameter falls back into the allowable range, the
termination condition ceases, or when the bq2060A detects that the battery is no longer being charged.
OVER_TEMP_ALARM bit is set when the bq2060A detects that the internal battery temperature is greater than
or equal to the MaxT limit. This bit is cleared when the internal temperature falls back into the acceptable range.
TERMINATE_DISCHARGE_ALARM bit is set when the bq2060A detects Voltage() ≤ EDV0, the CVUV bit in
Pack Status is set (Li-ion cell voltage has dropped below the limit programmed in Cell Under / Over Voltage), or
RemainingCapacity() = 0. The bit is cleared when Voltage() > EDV0 or CVUV bit is cleared, and
RemainingCapacity() > 0.
REMAINING_CAPACITY_ALARM bit is set when the bq2060A detects that RemainingCapacity() is less than
that set by the RemainingCapacityAlarm() function. This bit is cleared when the value set by the
RemainingCapacityAlarm() function is lower than RemainingCapacity().
REMAINING_TIME_ALARM bit is set when the bq2060A detects that the estimated remaining time at the
present discharge rate is less than that set by the RemainingTimeAlarm() function. This bit is cleared when the
value set by the RemainingTimeAlarm() function is lower than the AverageTimeToEmpty().
Status Bits
INITIALIZED bit is set when the bq2060A has detected a valid load of EEPROM. It is cleared when the bq2060A
detects an improper EEPROM load.
DISCHARGING bit is set when the bq2060A determines that the battery is not being charged. This bit is cleared
when the bq2060A detects that the battery is being charged.
FULLY_CHARGED bit is set when the bq2060A detects a primary charge termination or an overcharged
condition. It is cleared when RelativeStateOfCharge() ≤ the programmed Fully Charged Clear % in EE 0x4c.
FULLY_DISCHARGED bit is set when Voltage() ≤ EDV2 threshold, or RemainingCapacity() < Full Charge
Capacity*BatteryLow%. This bit is cleared when the Relative StateOfCharge() is ≥ 20%.
ERROR CODES
DESCRIPTION
OK
The bq2060A processed the function code without detecting any errors.
Busy
The bq2060A is unable to process the function code at this time.
Reserved
The bq2060A detected an attempt to read or write to a function code reserved by this version of the specification. The
bq2060A detected an attempt to access an unsupported optional manufacturer function code.
Unsupported The bq2060A does not support this function code which is defined in this version of the specification.
AccessDenied The bq2060A detected an attempt to write to a read-only function code.
Over/Underflow The bq2060A detected a data overflow or underflow.
BadSize
The bq2060A detected an attempt to write to a function code with an incorrect data block.
UnknownError The bq2060A detected an unidentifiable error.
