LTC3882
PMBus COMMAND DETAILS (Telemetry)
MFR_VIN_PEAK
The MFR_VIN_PEAK command reports the highest voltage, in volts, measured for READ_VIN. This peak value can be
reset by a MFR_CLEAR_PEAKS command.
This read-only command has two data bytes in Linear_5s_11s format.
READ_VOUT
The READ_VOUT command returns the output voltage measured at the V_SENSE± pins in volts.
This read-only command has two data bytes in Linear_16u format.
MFR_VOUT_PEAK
The MFR_VOUT_PEAK command reports the highest voltage, in volts, measured for READ_VOUT. This peak value can
be reset by a MFR_CLEAR_PEAKS command.
This read-only command has two data bytes in Linear_16u format.
READ_IOUT
The READ_IOUT command returns the output current in amperes. This value is computed from:
• The differential voltage measured across the I_SENSE± pins
• The IOUT_CAL_GAIN value
• The MFR_IOUT_CAL_GAIN_TC value
• The READ_TEMPERATURE_1 value
• The MFR_TEMP_1_GAIN value
• The MFR_TEMP_1_OFFSET value
This read-only command has two data bytes in Linear_5s_11s format.
MFR_IOUT_PEAK
The MFR_IOUT_PEAK command reports the highest current, in amperes, calculated for READ_IOUT. This peak value
can be reset by a MFR_CLEAR_PEAKS command.
This read-only command has two data bytes in Linear_5s_11s format.
READ_POUT
The READ_POUT command reports the output power in watts. The value is calculated from the product of the most
recent correlated output voltage and current readings.
This read-only command has two data bytes in Linear_5s_11s format.
