Temperature() (0x08); [0x08]
Description:
Returns the temperature (K)measured bythe bq2060.
Purpose:
The Temperature() function provides accurate cell tem-
peratures for use by battery chargers and thermal man-
agement systems. A battery charger can use the tem-
perature as a safety check. Thermal management sys-
tems may use the temperature because the battery is
one ofthe largest thermal sources in a system.

Voltage() (0x09); [0x09]
Description:
Returns the cell-pack voltage (mV).
Purpose:
The Voltage() function provides power management sys-
tems with an accurate battery terminal voltage. Power
management systems can use this voltage, along with
battery current information, to characterize devices they
control. This ability helps enable intelligent, adaptive
power-management systems.

Output:
Unsigned integer—battery terminal
voltage in mV.

Current() (0x0a); [0x0a]
Description:
Returns the current being supplied (or accepted)
through the battery’s terminals (mA).
Purpose:
The Current() function provides a snapshot for the
power management system of the current flowing into
or out of the battery. This information is of particular
use in power-management systems because they can
characterize individual devices and tune their operation
to actual system power behavior.

AverageCurrent() (0x0b); [0x0b]
Description:
Returns a value that approximates a one-minute rolling
average of the current being supplied (or accepted)
through the battery’s terminals (mA).
AverageCurrent() function will return meaningful val-
ues during the battery’s first minute ofoperation.

The AverageCurrent() function provides the average
current flowing into or out of the battery for the power
management system.
