PMBus COMMAND DETAILS
VIN_UV_WARN_LIMIT
The VIN_UV_WARN_LIMIT command sets the value of input voltage measured by the ADC that causes an input under-
voltage warning. This warning is disabled until the input exceeds the input startup threshold value set by the VIN_ON
command and the unit has been enabled. If the VIN Voltage drops below the VIN_OV_WARN_LIMIT the device:
• Sets the INPUT Bit Is the STATUS_WORD
• Sets the VIN Undervoltage Warning Bit in the STATUS_INPUT Command
• Notifies the Host by Asserting ALERT, unless Masked
VIN_ON
The VIN_ON command sets the input voltage, in Volts, at which the unit starts power conversion.
This command has two data bytes and is formatted in Linear_5s_11s format.
VIN_OFF
The VIN_OFF command sets the input voltage, in Volts, at which the unit stops power conversion.
This command has two data bytes and is formatted in Linear_5s_11s format.
MFR_RVIN
The MFR_RVIN command is not available, MFR_RVIN is set at factory assembly with 1Ω.
This command has two data bytes and is formatted in Linear_5s_11s format.
