Updates: On-the-fly The VOUT_OV_FAULT_RESPONSE command instructs the device on what action to take in response to an output over-voltage fault.
Figure 8-15 VOUT_OV_FAULT_RESPONSE Table 8-21 VOUT_OV_FAULT_RESPONSE Field Descriptions| Bit | Field | Type | Reset | Description |
|---|
| 7-6 | RESERVED | R | 0h | Reserved |
| 5-3 | RS_OV | R/W | X | Output voltage over voltage retry setting. On reset the value will be determined by NVM. - 0h = The device does not attempt to restart. The output remains disabled until the fault is cleared (See section 10.7 of the PMBus spec.)
- 7h = The device goes through a normal startup (Soft start) continuously, without limitation, until it is commanded off or bias power is removed or another fault condition causes the unit to shutdown. Data Validity: Any value other than 000 or 111 will not be accepted and such an attempt shall be considered as invalid data or unsupported data (ivd) and the device shall respond as described in ivd. Note, that since all 3 bits must be the same, only one (bit 5) is stored in EEPROM.

| 2-0 | TD_OV | R | 0h | Output over voltage retry time delay setting.
- 0h = A zero value for the Retry time delay setting means that the unit does not delay a restart. This is only supported when Restart is disabled by RS_OV[2:0] = 000. The output remains disabled until the fault is cleared (See section 10.7 of the PMBus spec.)
