| |
| maxim,constant-microvolt: |
| description: | |
| Battery constant voltage in uV. The charger will operate in fast |
| charge constant current mode till battery voltage reaches this level. |
| Then the charger will switch to fast charge constant voltage mode. |
| Also vsys (system voltage) will be set to this value when DC power is |
| supplied but charger is not enabled. |
| Valid values: 3650000 - 4400000, step by 25000 (rounded down) |
| minimum: 3650000 |
| maximum: 4400000 |
| default: 4200000 |
| |
| maxim,min-system-microvolt: |
| description: | |
| Minimal system voltage in uV. |
| enum: [3000000, 3100000, 3200000, 3300000, 3400000, 3500000, |
| 3600000, 3700000] |
| default: 3600000 |
| |
| maxim,thermal-regulation-celsius: |
| description: | |
| Temperature in Celsius for entering high temperature charging mode. |
| If die temperature exceeds this value the charging current will be |
| reduced by 105 mA/Celsius. |
| enum: [70, 85, 100, 115] |
| default: 100 |
| |
| maxim,battery-overcurrent-microamp: |
| description: | |
| Overcurrent protection threshold in uA (current from battery to |
| system). |
| Valid values: 2000000 - 3500000, step by 250000 (rounded down) |
| minimum: 2000000 |
| maximum: 3500000 |
| default: 3500000 |
| |
| maxim,charge-input-threshold-microvolt: |
| description: | |
| Threshold voltage in uV for triggering input voltage regulation loop. |
| If input voltage decreases below this value, the input current will |
| be reduced to reach the threshold voltage. |
| enum: [4300000, 4700000, 4800000, 4900000] |
| default: 4300000 |
