| 28 | shunt-resistor-micro-ohms: |
| 29 | description: |
| 30 | The value of current sense resistor in microohms. If not provided, |
| 31 | the current reading and overcurrent alert is disabled. |
| 32 | |
| 33 | adi,shutdown-threshold-microamp: |
| 34 | description: |
| 35 | Specifies the current level at which an over current alert occurs. |
| 36 | If not provided, the overcurrent alert is configured to max ADC range |
| 37 | based on shunt-resistor-micro-ohms. |

| 39 | adi,vrange-high-enable: |
| 40 | description: |
| 41 | Specifies which internal voltage divider to be used. A 1 selects |
| 42 | a 7:2 voltage divider while a 0 selects a 14:1 voltage divider. |
