|
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.

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.

description: |
|
|
Overcurrent protection threshold in uA (current from battery to
|
|
system).

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.
