LTC3883/LTC3883-1
PMBus Command Details
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.
MFR_READ_ICHIP
The MFR_READ_ICHIP command returns the measured input current, in Amperes, used by the LTC3883.
This command has two data bytes and is formatted in Linear_5s_11s format.
MFR_READ_IIN_CHAN
The MFR_READ_IIN_CHAN command returns the calculated value of the input current, in Amperes, as a function of
READ_IOUT and DUTY_CYCLE. For accurate values at low currents, the part must be in continuous conduction mode.
If DCR sensing is used, the accuracy of the inductor DCR resistance, IOUT_CAL_GAIN, will effect the accuracy of the
MFR_READ_IIN command.
This command has two data bytes and is formatted in Linear_5s_11s format.
MFR_TEMPERATURE_2_PEAK
The MFR_TEMPERATURE_2_PEAK command reports the highest temperature, in degrees Celsius, reported by the
READ_TEMPERATURE_2 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.
