The charger can be used to charge a battery, power a system or both. The charger has three phases of charging: Pre-charge to recover a fully discharged battery, fast-charge constant current to supply the buck charge safely and voltage regulation to safely reach full capacity.

The part is considered “dead” and all the pins are high impedance. Once the IN voltage rises above the UVLO threshold the IC will enter Sleep Mode or Active mode depending on the OUT pin (battery) voltage.

The TS function for bq24090, bq24091 and bq24095 follow the classic temperature range and disable charge when the battery temperature outside of the 0°C and 45°C operating temperature window. The TS function for bq24092 and bq24093 are designed to follow the new JEITA temperature standard for Li-Ion and Li-Pol batteries.

If the battery is present, the charge current will terminate.

The time from full to discharge can be calculated by dividing the Amp-Hour Capacity of the battery by the leakage current. For a 0.75AHr battery and a 10μA leakage current (750mAHr/0.010mA = 75000 Hours), it would take 75k hours or 8.8 years to discharge.
