PMBus COMMAND DETAILS
READ_PIN
The READ_PIN command is a reading of the DC/DC converter input power in Watts. PIN is calculated based on the
most recent input voltage and current reading.
This read-only command has 2 data bytes and is formatted in Linear_5s_11s format.
MFR_PIN_ACCURACY
The MFR_PIN_ACCURACY command returns the accuracy, in percent, of the value returned by the READ_PIN command.
There is one data byte. The value is 0.1% per bit which gives a range of ±0.0% to ±25.5%.
This read-only command has one data byte and is formatted as an unsigned integer.
MFR_IOUT_PEAK
The MFR_IOUT_PEAK command reports the highest current, in amperes, reported by the READ_IOUT measurement.
This command is cleared using the MFR_CLEAR_PEAKS command.
This read-only command has two data bytes and is formatted in Linear_5s_11s format.
MFR_VOUT_PEAK
The MFR_VOUT_PEAK command reports the highest voltage, in volts, reported by the READ_VOUT measurement.
This command is cleared using the MFR_CLEAR_PEAKS command.
This read-only command has two data bytes and is formatted in Linear_16u format.
MFR_VIN_PEAK
The MFR_VIN_PEAK command reports the highest voltage, in volts, reported by the READ_VIN measurement.
This command is cleared using the MFR_CLEAR_PEAKS command.
This read-only command has two data bytes and is formatted in Linear_5s_11s format.
MFR_TEMPERATURE_1_PEAK
The MFR_TEMPERATURE_1_PEAK command reports the highest temperature, in degrees Celsius, reported by the
READ_TEMPERATURE_1 measurement.
This command is cleared using the MFR_CLEAR_PEAKS command.
This read-only command has two data bytes and is formatted in Linear_5s_11s format.
MFR_READ_IIN_PEAK
The MFR_READ_IIN_PEAK command reports the highest current, in Amperes, reported by the READ_IIN measurement.
This command is cleared using the MFR_CLEAR_PEAKS command.
This command has two data bytes and is formatted in Linear_5s_11s format.
