9.3.7.2 Battery Charging Profile
The device charges the battery in five phases: battery short, preconditioning, constant current, constant voltage and top-off trickle charging (optional). At the beginning of a charging cycle, the device checks the battery voltage and regulates current and voltage accordingly.
Table 9-4 Charging Current Setting
| VBAT | CHARGING CURRENT | REGISTER DEFAULT SETTING | CHRG_STAT |
|---|---|---|---|
| < 2.2 V | ISHORT | 100 mA | 01 |
| 2.2 V to 3 V | IPRECHG | 180 mA | 01 |
| > 3 V | ICHG | 2.048 A | 10 |
If the charger device is in DPM regulation or thermal regulation during charging, the actual charging current will be less than the programmed value. in this case, termination is temporarily disabled and the charging safety timer is counted at half the clock rate.
