FullChargeCapacity( )/|AtRate( )|
Invalid Data Indication:
65,535 indicates the AtRate

0.
AtRateTimeToEmpty( ) (0x06)
Description:
Returns the predicted remaining operating time if the battery is discharged at the AtRate( ) value.
Purpose:
The AtRateTimeToEmpty( ) function is part of a two-function call-set used to determine the remaining
operating time at the AtRate( ) value. The bq2083V1P2 updates AtRateTimeToEmpty( ) within 5 ms after the
SMBus host sets the AtRate( ) value. The bq2083V1P2 automatically updates AtRateTimeToEmpty( ) based on
the AtRate( ) value every 1 s.
SMBus protocol:
Read word
Output:
Unsigned integer
estimated operating time left.
Units:

FullChargeCapacity/|AtRate( )|
Invalid Data Indication:
65,535 indicates AtRate
≥
0.
AtRateOK( ) (0x07)
Description:
Returns a boolean value that indicates whether or not the battery can deliver the AtRate( )value
of
additional
energy for 10 seconds. If the AtRate value is zero or positive, the AtRateOK( ) function always returns
OK (logic 1).
Purpose:
The AtRateOK( ) function is part of a two-function call-set used by power management systems to
determine if the battery can safely supply enough energy for an additional load. The bq2083V1P2 updates
AtRateOK( ) within 5 ms after the SMBus host sets the AtRate( ) value. The bq2083V1P2 automatically updates
AtRateOK( ) based on the At Rate( ) value every 1 second.
SMBus protocol:
Read word
Output:
Boolean—indicates if the battery can supply the
additional
energy requested.
Units:
Boolean
Range:
1, 0
Granularity:
Not applicable
Accuracy:
Not applicable
Temperature( ) (0x08)
Description:
Returns the temperature (K) measured by the bq2083V1P2.
Purpose:
The Temperature( ) function provides accurate cell temperatures for use by battery chargers and
thermal management systems. A battery charger can use the temperature as a safety check. Thermal
management systems may use the temperature because the battery is one of the largest thermal sources in a
system.
SMBus protocol:
Read word
Output:
Unsigned integer—cell temperature in tenth-degree Kelvin increments.
Units:
0.1
°
K
Range:
0 to +6553.5
