| 23 | maxim,constant-microvolt: |
| 24 | description: | |
| 25 | Battery constant voltage in uV. The charger will operate in fast |
| 26 | charge constant current mode till battery voltage reaches this level. |
| 27 | Then the charger will switch to fast charge constant voltage mode. |
| 28 | Also vsys (system voltage) will be set to this value when DC power is |
| 29 | supplied but charger is not enabled. |

| 60 | description: | |
| 61 | Threshold voltage in uV for triggering input voltage regulation loop. |
| 62 | If input voltage decreases below this value, the input current will |
| 63 | be reduced to reach the threshold voltage. |
