description: |
The ALRT pin, an open-drain interrupt.
maxim,rsns-microohm:
$ref: /schemas/types.yaml#/definitions/uint32
description: |
Resistance of rsns resistor in micro Ohms (datasheet-recommended value is 10000).
Defining this property enables current-sense functionality.
maxim,cold-temp:
$ref: /schemas/types.yaml#/definitions/uint32
description: |
Temperature threshold to report battery as cold (in tenths of degree Celsius).
Default is not to report cold events.
maxim,over-heat-temp:
$ref: /schemas/types.yaml#/definitions/uint32
description: |
Temperature threshold to report battery as over heated (in tenths of degree Celsius).
Default is not to report over heating events.
maxim,dead-volt:
$ref: /schemas/types.yaml#/definitions/uint32
description: |
Voltage threshold to report battery as dead (in mV).
Default is not to report dead battery events.
maxim,over-volt:
$ref: /schemas/types.yaml#/definitions/uint32
description: |
Voltage threshold to report battery as over voltage (in mV).
Default is not to report over-voltage events.
