Voltage:
The bq2060 requests the pre-charge charge
rate when Voltage() drops below the EDV0 threshold
(compensated or fixed EDVs). Once requested, a
pre-charge rate remains until Voltage() increases
above
the
EDVF
threshold.

T emperature:
The bq2060 requests the pre-charge
rate when Temperature() is between 0°C and 5°C.
Temperature() must rise above 5°C before the bq2060
requests thefast-chargerate.
Charge Suspension
The bq2060 may temporarily suspend charge if it de-
tects a charging fault. A charging fault includes the fol-
lowing conditions.
Overcurrent:
the bq2060 measures the charge current tobe more than
the
Overcurrent Margin
above the ChargingCurrent().
Overcurrent Margin
is programmed in EE 0x49. On
detecting an overcurrent condition, the bq2060 sets the
ChargingCurrent() to zero and sets the TERMINbelow

CHARGE_ALARM bit when it detects that the battery
is no longer being charged (DISCHARGING bit set in
