PRODUCTION DATA
The VIN_OFF command sets the value of the input voltage at which the unit should stop operation. Values are mapped to the nearest supported increment. Values outside the supported range is treated as invalid data and causes the device to set the CML bit in the STATUS_BYTE and the invalid data (ivd) bit in the STATUS_CML registers. The value of VIN_OFF remains unchanged during an out-of-range write attempt. The contents of this register can be stored to non-volatile memory using the STORE_USER_ALL command.
The supported VIN_OFF values are:
| 4 (default) | 4.25 | 4.5 | 4.75 | 5 |
| 5.25 | 5.5 | 5.75 | 6 | 6.25 |
| 6.5 | 6.75 | 7 | 7.25 | 7.5 |
| 8 | 8.25 | 8.5 | 8.75 | 9 |
| 9.25 | 9.75 | 10.25 | 10.75 | 11.25 |
| 11.75 | 12 | 13.75 | 14.75 | 15.75 |
VIN_ON must be set higher than VIN_OFF. Attempting to write either VIN_ON lower than VIN_OFF or VIN_OFF higher than VIN_ON results in the new value being rejected, SMBALERT being asserted along with the CML bit in STATUS_BYTE and the invalid data bit in STATUS_CML.
