LTC3882
PMBus COMMAND DETAILS (Output Voltage and Limits)
VOUT_OV_WARN_LIMIT
The VOUT_OV_WARN_LIMIT command sets the value, in volts, of the output voltage measured by the ADC at the
V_SENSE± pins that causes an output overvoltage warning. If the VOUT_OV_WARN_LIMIT is exceeded, the device:
• Sets the VOUT Bit in the STATUS_WORD
• Sets the V_OUT Overvoltage Warning Bit in the STATUS_VOUT Command
• Notifies the Host by Asserting ALERT, Unless Masked
This command has two data bytes in Linear_16u format.
VOUT_UV_WARN_LIMIT
The VOUT_UV_WARN_LIMIT command sets the value, in volts, of the output voltage measured by the ADC at the
V_SENSE± pins that causes an output undervoltage warning. If the VOUT_UV_WARN_LIMIT is exceeded, the device:
• Sets the VOUT Bit in the STATUS_WORD
• Sets the V_OUT Undervoltage Warning Bit in the STATUS_VOUT Command
• Notifies the Host by Asserting ALERT, Unless Masked
This command has two data bytes in Linear_16u format.
VOUT_UV_FAULT_LIMIT
The VOUT_UV_FAULT_LIMIT command sets the value of the output voltage measured by the UV supervisor at the
V_SENSE± pins, in volts, which causes an output undervoltage fault.
This command has two data bytes in Linear_16u format.
