8.4.8.2 Log Only The UCD9081 can be configured to log a fault and take no additional action. For more information, see Error Logging. 8.4.8.3 Retry n Times The UCD9081 can be configured to attempt to restart a rail up to n times (n = 0,1,2,3, or 4) in response to a ...
Connect a jumper wire from a pull-up pin in J17 or J18 to the GPI pin. Observe that the LEDs of the 16 LGPO pins are lit after 960 ms. Also observe that the corresponding GPI Fault is logged in the Status page. Then disconnect the logic input signal from the GPI pin. Observe ...
This log tracks the peak internal and external temperature sensor measurements, peak current measurements and fault history. The PMBus commands and data format for the Data Logging can be found in the UCD92xx PMBus Command Reference (SLUU337). 8.4 Device Functional Modes 8.4.1 4-Bit VID Mode...
Figure 8. Fusion GUI Monitor Page The UCD9090 also has status registers for each rail and the capability to log faults to flash memory for use in system troubleshooting. This is helpful in the event of a power-supply or system failure. The status registers (Figure 9) and the fault log ...
Each UCD9080 rail can be configured to shut down based on a monitored alarm event (sustained overvoltage, sustained undervoltage, or rail did not start) and in a configurable manner. The options for rail shutdown are as follows: • Ignore • Log only • Sequence • Retry 1 time ...
Optionally, connect the power-good output of the last device to a MON pin of the first device. The rails controlled by a device have dependency on the previous device's power-good output. This way, the rails controlled by multiple devices can be sequenced. Also, the de-assertion of a ...
4.2.14 SaveRailLog The SaveRailLog field in the configuration parameters specifies whether each rail is marked to write the error log to flash upon rail failure. If the rail is marked this way, then a shutdown of this rail is logged info non-volatile memory. In this case, the NVERRLOG...
Data Logging The UCD9246 maintains a data log in non-volatile memory. This log tracks the peak internal and external temperature sensor measurements, peak current measurements and fault history. The LOGGED_PEAKS and LOGGED_FAULTS PMBus commands and data format for the Data Logging can be found ...
