VIN_ON
The VIN_ON command sets the input voltage, in volts, required to start power conversion.
This command has two data bytes in Linear_5s_11s format.
VIN_OFF
The VIN_OFF command sets the minimum input voltage, in volts, at which power conversion stops.
This command has two data bytes in Linear_5s_11s format.
VIN_OV_FAULT_LIMIT
The VIN_OV_FAULT_LIMIT command sets the value of the input voltage measured by the ADC, in volts, that causes
an input overvoltage fault.
This command has two data bytes in Linear_5s_11s format.
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_UV_WARN_LIMIT is then exceeded, the device:
• Sets the INPUT Bit in the STATUS_WORD
• Sets the VIN Undervoltage Warning Bit in the STATUS_INPUT Command
• Notifies the Host by Asserting ALERT, Unless Masked
