2.9.52 Sleep Voltage Time
During SLEEP mode, temperature and voltage measurements will be taken in Sleep Voltage Time
intervals. The default setting is 20 s.
2.9.53 Sleep Current Time
During SLEEP mode, current will be measured in Sleep Current Time intervals. The default value is 20 s.
2.9.54 Dsg Current Threshold (Discharge Detection Threshold)
The bq34210-Q1 device enters DISCHARGE mode from RELAXATION mode or CHARGE mode if
Current() < (–) Dsg Current Threshold.
2.9.55 Chg Current Threshold (Charge Detection Threshold)
The bq34210-Q1 device enters CHARGE mode from RELAXATION mode or DISCHARGE mode if
Current() > Chg Current Threshold.
2.9.56 Quit Current
The bq34210-Q1 device enters RELAXATION mode from CHARGE mode if Current() goes below
Quit Current for Charge Relax Time. The device enters RELAXATION mode from DISCHARGE mode if
Current() goes above (–)Quit Current for Discharge Relax Time.
2.9.57 Discharge Relax Time
The bq34210-Q1 device enters RELAXATION mode from DISCHARGE mode if Current() goes above
(–)Quit Current for at least Discharge Relax Time.
NOTE: To optimize power consumption, it is recommended to set Discharge Relax Time to 0 so
the device enters RELAXATION mode immediately when Current() rises above
(–)Quit Current.
2.9.58 Charge Relax Time
The bq34210-Q1 device enters RELAXATION mode from CHARGE mode if Current() goes below
Quit Current for at least Charge Relax Time.
2.9.59 Quit Relax Time
The Quit Relax Time is the delay time to exit RELAXATION. If current is greater than Chg Current
Threshold or less than Dsg Current Threshold and this condition is maintained for Quit Relax Time,
then exiting RELAXATION is permitted. This is useful in applications with low duty cycle dynamic loads.
2.9.60 OT Charge
The bq34210-Q1 device sets the [OTC] flag in BatteryStatus() if the pack Temperature() is equal to or
higher than the Over Temp Chg threshold.
2.9.60.1 OT Charge Time
If the [OTC] condition exists for a time that exceeds the OT Chg Time period, the bq34210-Q1 device
goes into an overtemperature charge condition. This function is disabled if OT Chg Time is set to 0.
In an overtemperature charge condition, the ChargingVoltage() and ChargingCurrent() are set to 0, and
the [OTC] bit is set in the BatteryStatus() register.
