PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The device charges the battery in three phases: preconditioning, constant current, constant voltage. The device charges the battery based on charge voltage set by the VSET pin and charge current set by the ICHG pin as well as actual battery voltage. The battery charging profile is shown in Figure 8-1.
MODE | BATTERY VOLTAGE VBAT | CHARGE CURRENT | TYPICAL VALUE |
---|---|---|---|
Battery Short | VBAT < VBAT_SHORT | Charge Inhibited | -1.5uA |
Precharge | VBAT_SHORT < VBAT < VBAT_LOWV | IPRECHG | 10% of ICHG ( IPRE > 63mA ) |
Fast Charge | VBAT_LOWV < VBAT | ICHG | Set by ICHG resistor |
