Alarm Bits
Set When:
Bit Name
Reset When:
OVER_CHARGE_ALARM
bq2092 detects over-temperature or
T/
t.(
Note: valid charge termina-
tion
).
bq2092 detects over-current, over-
voltage, over-temperature, or
T/
t
conditions exist during charge.
Charging current is set to zero, indi-
cating a charge suspend.
bq2092 detects the rate-of-
temperature increase is above the pro-
grammed value (valid termination)
bq2092 detects that its internal tem-
perature is greater than the pro-
grammed value (valid termination).
A discharge occurs or when
T/
t, or
over-temperature, ceases during
charge.
TERMINATE_CHARGE_ALARM
A discharge occurs or when all condi-
tions causing the event cease.
T/
t_ALARM
The temperature rise falls below the
programmed rate.
OVER_TEMP_ALARM
Internal temperature falls below
50°C.
TERMINATE_DISCHARGE_ALARM
bq2092 determines that it has sup-
plied all the charge that it can with-
out being damaged (EDVF).
V
BAT
> V
EDVF
signifying that the
battery has reached a state of charge
sufficient for it to once again safely
supply power.
Either the value set by the Remain-
ingCapacityAlarm() function is lower
than the Remaining Capacity() or
the RemainingCapacity() is in-
creased by charging.
Either the value set by the Remain-
ingTimeAlarm() function is lower
than the AverageTimeToEmpty() or
a valid charge is detected.
REMAINING_CAPACITY_ALARM
bq2092 detects that the Remaining-
Capacity() is less than that set by
the RemainingCapacity() function.
REMAINING_TIME_ALARM
bq2092 detects that the estimated
remaining time at the present dis-
charge rate is less than that set by
the RemainingTimeAlarm() function.
Status Bits
Set When:
bq2092 is set when the bq2092 has
reached a full or empty state.
bq2092 determines that it is not be-
ing charged.
bq2092 determines a valid charge
termination. RM will then be set to
full charge percentage if necessary.
bq2092 determines that it has
supplied all the charge that it can
without being damaged (that is, con-
tinued use will result in permanent
capacity loss to the battery)
Bit Name
Reset When:
INITIALIZED
Battery detects that power-on or
user-initiated reset has occurred.
Battery detects that it is being
charged.
DISCHARGING
FULLY_CHARGED
RM discharges below the full charge
percentage
FULLY_DISCHARGED
RelativeStateOfCharge is greater
than or equal to 20%
