PMBus Power-Supply Data Logger
IOUT_OC_FAULT_LIMIT (4Ah)
The IOUT_OC_FAULT_LIMIT command sets the value of the current that causes an overcurrent fault. The monitored
current must drop by at least 5% below the limit before the fault is allowed to clear. This fault is masked until the
current is below this limit for the first time. The 2 data bytes are in DIRECT format. In response to violation of the
IOUT_OC_FAULT_LIMIT, the device does the following:
1) Sets the IOUT_OC bit in STATUS_BYTE.
2) Sets the IOUT_OC and MFR bits in STATUS_WORD.
3) Sets the OC_FAULT bit in STATUS_MFR_SPECIFIC.
4) Responds as specified in the MFR_FAULT_RESPONSE.
The factory default value for IOUT_OC_FAULT_LIMIT is 0000h. This value disables the device from measuring current
and instead selects voltage monitoring on this channel (if the channel is enabled with the MFR_MODE command). Any
nonzero positive value written to IOUT_OC_FAULT_LIMIT causes the device to enable current measurement instead of
Table 8. IOUT_OC_FAULT_LIMIT
IOUT_OC_FAULT_LIMIT VALUE
8000h to FFFFh
0000h
0001h to 7FFFh
DEVICE RESPONSE (ON THE ASSOCIATED PAGE)
Negative values are invalid.
Current measurement disabled (voltage measurement enabled).
Current measurement enabled (voltage measurement disabled).
OT_FAULT_LIMIT (4Fh)
The OT_FAULT_LIMIT command sets the temperature, in degrees Celsius, of the selected temperature sensor at which
an overtemperature fault is detected. The monitored temperature must drop by at least 4 N C below the limit before the
fault is allowed to clear. This fault is masked until the temperature is below this limit for the first time. The 2 data bytes
are in DIRECT format. In response to the OT_FAULT_LIMIT being exceeded, the device does the following:
1) Sets the TEMPERATURE bit in STATUS_BYTE.
2) Sets the TEMPERATURE and MFR bits in STATUS_WORD.
3) Sets the OT_FAULT bit in STATUS_MFR_SPECIFIC register.
4) Responds as specified in the MFR_FAULT_RESPONSE.
The factory default value for OT_FAULT_LIMIT is 0000h. This value disables the device from measuring temperature on
the selected temperature sensor. Any nonzero positive value written to OT_FAULT_LIMIT causes the device to enable
temperature measurement.
