| shunt-resistor-micro-ohms: |
| description: Shunt resistor value in micro-ohms. Since device has internal |
| 16-bit RSHUNT register with 10 uOhm LSB, the maximum value is capped at |
| 655.35 mOhm. |
| minimum: 100 |
| default: 1000 |
| maximum: 655350 |
| |
| st,alert-polarity-active-high: |
| $ref: /schemas/types.yaml#/definitions/flag |
| description: Default value is 0 which configures the normal polarity of the |
| ALERT pin, being active low open-drain. Setting this to 1 configures the |
| polarity of the ALERT pin to be inverted and active high open-drain. |
| Specify this property to set the alert polarity to active-high. |
