ChargingVoltage() (0x15); [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
operating point. Together, these functions permit the bq2060A 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: Write Word
Output:
Unsigned integer—charger output voltage in mV.
• Units: mV
• Range: 0 mV to 65,535 mV
• Granularity: 1 mV
• Accuracy: not applicable
• Invalid Data Indication: 65,535 indicates that the charger should operate as a current source outside its
maximum regulated voltage range.
BatteryStatus()(0x16); [0x16]
Description: Returns the bq2060 status word (flags). Some of the BatteryStatus() flags
(REMAINING_CAPACITY_ALARM and REMAINING_TIME_ALARM) are calculated based on either current or
power depending on the setting of the BatteryMode() CAPACITY_MODE bit. This is important because use of
the wrong calculation mode may result in an inaccurate alarm.
Purpose: The BatteryStatus() function is used by the power management system to get alarm and status bits, as
well as error codes from the bq2060A. This is basically the same information broadcast to both the SMBus Host
and the Smart Battery Charger by the AlarmWarning() function except that the AlarmWarning() function sets the
Error Code bits all high before sending the data.
SMBus Protocol: Read Word
Input/Output:
Unsigned integer—Status Register with alarm conditions bit-mapped as follows:
