|
|
|
shunt-resistor-micro-ohms:
|
|
description:
|
|
The value of curent sense resistor in microohms. If not provided,
|
|
the current reading and overcurrent alert is disabled.
|
|
|
|
adi,shutdown-threshold-microamp:
|
|
description:
|
|
Specifies the current level at which an over current alert occurs.
|
|
If not provided, the overcurrent alert is configured to max ADC range
|
|
based on shunt-resistor-micro-ohms.
|
|
|
|
adi,vrange-high-enable:
|
|
description:
|
|
Specifies which internal voltage divider to be used. A 1 selects
|
|
a 7:2 voltage divider while a 0 selects a 14:1 voltage divider.
