When the pin is asserted, device does not alert PMBUS_Alert pin, not response for faults, log faults defined in the Table 7-6. The rail sequence on/off dependency conditions are ignored, as soon as the sequence on/off timeout is expired, the rails will be sequenced on or off accordingly regardless of the timeout action, if the sequence on/off timeout value is set to 0, the rails is sequenced on or off immediately. The fault pins do not pull the fault bus low. The LGPOs affected by these events should be back to it original states.
Events | Description |
---|---|
VOUT_OV_FAULT | Voltage Rail is over OV fault threshold |
VOUT_OV_WARNING | Voltage Rail is over OV warning threshold |
VOUT_UV_FAULT | Voltage Rail is under UV fault threshold |
VOUT_UV_WARNING | Voltage Rail is under UV warning threshold |
TON_MAX | Voltage Rail fails to reach power good threshold in predefined period. |
TOFF_MAX Warning | Voltage rail fails to reach power not good threshold in predefined period |
IOUT_OC_FAULT | Current Rail is over OC fault threshold |
IOUT_OC_WARNING | Current Rail is under OC warning threshold |
IOUT_UC | Current Rail is under UC fault threshold |
OT_FAULT | Temperature Rail has over OT fault threshold |
OT_WARNING | Temperature Rail has over OT warning threshold |
All GPI de-asserted | No logging and fault response, but the function of the GPI is not ignored. |
SYSTEM_WATCHDOG_TIMEOUT | System watch timeout |
RESEQUENCE_ERROR | Rail fails to resequence |
SEQ_ON_TIMEOUT | Rail fails to meeting sequence on dependency in predefined period |
SEQ_OFF_TIMEOUT | Rail fails to meeting sequence on dependency in predefined period |
SLAVE_FAULT | Rail is shut down due to that its master has fault |
