PMBus 6-Channel Power-Supply Manager
USER NOTE: On the device, the full-scale ADC voltage is 1.225V. The value of the sense resistor and current-
sense amplifier gain must be scaled appropriately.
VOUT_OV_FAULT_LIMIT (40h)
The VOUT_OV_FAULT_LIMIT command sets the value of the output voltage that causes an output overvoltage fault.
The 2 data bytes are in DIRECT format. In response to the VOUT_OV_FAULT_LIMIT being exceeded, the device does
the following:
1) Sets the VOUT_OV bit in STATUS_BYTE.
2) Sets the VOUT_OV and VOUT bits in STATUS_WORD.
3) Sets the VOUT_OV_FAULT bit in STATUS_VOUT.
4) Responds as specified in the MFR_FAULT_RESPONSE.
5) Notifies the host through ALERT assertion (if enabled in MFR_MODE).
VOUT_OV_WARN_LIMIT (42h)
The VOUT_OV_WARN_LIMIT command sets the value of the output voltage that causes an output-voltage high warn-
ing. This value is typically less than the output overvoltage threshold in VOUT_OV_FAULT_LIMIT. The 2 data bytes are
in DIRECT format. In response to the VOUT_OV_WARN_LIMIT being exceeded, the device does the following:
1) Sets the NONE OF THE ABOVE bit in STATUS_BYTE.
2) Sets the NONE OF THE ABOVE and VOUT bits in STATUS_WORD.
3) Sets the VOUT_OV_WARN bit in STATUS_VOUT.
4) Notifies the host using ALERT assertion (if enabled in MFR_MODE).
VOUT_UV_WARN_LIMIT (43h)
The VOUT_UV_WARN_LIMIT command sets the value of the output voltage that causes an output-voltage low warning.
This value is typically greater than the output undervoltage fault threshold in VOUT_UV_FAULT_LIMIT. This warning is
masked until the output voltage reaches the programmed VOUT_UV_FAULT for the first time and also during turn-off
when the power supply is disabled. The 2 data bytes are in DIRECT format. In response to violation of the VOUT_UV_
WARN_LIMIT, the device does the following:
1) Sets the NONE OF THE ABOVE bit in STATUS_BYTE.
2) Sets the NONE OF THE ABOVE and VOUT bits in STATUS_WORD.
3) Sets the VOUT_UV_WARN bit in STATUS_VOUT.
4) Notifies the host using ALERT assertion (if enabled in MFR_MODE).
VOUT_UV_FAULT_LIMIT (44h)
The VOUT_UV_FAULT_LIMIT command sets the value of the output voltage that causes an output undervoltage fault.
This fault is masked until the output voltage reaches the programmed VOUT_UV_FAULT for the first time and also
during turn-off when the power supply is disabled. The VOUT_UV_FAULT_LIMIT threshold is also used to determine if
TON_MAX_FAULT_LIMIT is exceeded. The 2 data bytes are in DIRECT format. In response to violation of the VOUT_
UV_FAULT_LIMIT, the device does the following:
1) Sets the NONE OF THE ABOVE bit in STATUS_BYTE.
2) Sets the NONE OF THE ABOVE and VOUT bits in STATUS_WORD.
3) Sets the VOUT_UV_FAULT bit in STATUS_VOUT.
