active-semi,input-voltage-threshold-microvolt:
description: |
Specifies the charger's input over-voltage threshold value.
Despite the name, specified values are in millivolt (mV).
Defaults to 6.6 V
enum: [ 6600, 7000, 7500, 8000 ]
active-semi,precondition-timeout:
$ref: /schemas/types.yaml#/definitions/uint32
description: |
Specifies the charger's PRECONDITION safety timer setting value in minutes.
If 0, it means to disable this timer.
Defaults to 40 minutes.
enum: [ 0, 40, 60, 80 ]
active-semi,total-timeout:
$ref: /schemas/types.yaml#/definitions/uint32
description: |
Specifies the charger's total safety timer setting value in hours;
If 0, it means to disable this timer;
Defaults to 3 hours.
