Range:
0 to 65,534 min
Granularity:
2 min or better
Accuracy:
0, +MaxError( )
*
FullChargeCapacity( ) / AverageCurrent( )
Invalid Data Indication:
65,535 indicates battery is not being discharged.
AverageTimeToFull( ) (0x13)
Description:
Returns a one-minute rolling average of the predicted remaining time until the battery reaches full
charge (minutes).
Purpose:
The AverageTimeToFull( ) function can be used by the SMBus host’s power management system to
aid in its policy. It may also be used to find out how long the system must be left on to achieve full charge.
SMBus protocol:
Read word
Output:
Unsigned integer
remaining time in minutes.
Units:
Minutes
Range:
0 to 65,534 minutes
Granularity:
2 minutes or better
Accuracy:
0, +MaxError( )
*
FullChargeCapacity( ) / AverageCurrent( )
Invalid Data Indication:
65,535 indicates the battery is not being charged.
ChargingCurrent( ) (0x14)
Description:
Returns the desired charging rate in mA.
Purpose:
The ChargingCurrent( ) function sets the maximum charge current of the battery. The
ChargingCurrent( ) value should be used in combination with the ChargingVoltage( ) value to set the charger’s
operating point. Together, these functions permit the bq2083V1P2 to dynamically control the charging profile
(current/voltage) of the battery. The bq2083V1P2 can effectively turn off a charger by returning a value of 0 for
this function. The charger may be operated as a constant-voltage source above its maximum regulated current
range by returning a ChargingCurrent( ) value of 65,535.
SMBus protocol:
Read word
Output:
Unsigned integer
maximum charger output current in mA.
Units:
mA
Range:
0 to 65,535 mA
Granularity:
1 mA
Accuracy:
Not applicable
Invalid Data Indication:
65,535 indicates that a charger should operate as a voltage source outside its maximum
regulated current range.
ChargingVoltage( ) (0x15)
Description:
Returns the desired charging voltage in mV.
Purpose:
The ChargingVoltage( ) function sets the maximum charge voltage of the battery. The
ChargingVoltage( ) value should be used in combination with the ChargingCurrent( ) value to set the charger’s
operating point. Together, these functions permit the bq2083V1P2 to dynamically control the charging profile
(current/voltage) of the battery. The charger may be operated as a constant-current source above its maximum
regulated voltage range by returning a ChargingVoltage( ) value of 65,535.
SMBus protocol:
Read word
Output:
Unsigned integer
charger output voltage in mV.
Units:
mV
Range:
0 to 65,535 mV
Granularity:
1mV
Accuracy:
Not applicable
Invalid Data Indication:
65,535 indicates the charger should operate as a current source outside its maximum
regulated voltage range.
