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 VSENSE± 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 master channel output current in amperes. This value is computed by applying

IOUT_CAL_GAIN to the voltage measured between ISENSE and IREF.

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.

MFR_TOTAL_IOUT

The MFR_TOTAL_IOUT command reports the total output current for all on-chip phases of the entire rail as defined by

MFR_PWM_CONFIG_LTC3888-1. The value is calculated from the sum of the individual phase IOUT ADC conversions.

If bit 6 of MFR_PWM_CONFIG_LTC3888-1 is set, PWM2-PWM7 report 0A regardless of the actual output load. Sums

are always reported by page, even if the master channel has been defined as a slave (see bit 4 of MFR_PWM_MODE_

LTC3888-1). Sums across IC boundaries are not supported.

This read-only command has two data bytes in Linear_5s_11s format.

MFR_READ_ALL_IOUT

The MFR_READ_ALL_IOUT command reports the output current for each of the eight phases on the LTC3888-1 using

block read protocol. Monitor ADC results are presented in order from PWM0 to PWM7. If bit 6 of MFR_PWM_CONFIG_

LTC3888-1 is set, PWM2-PWM7 report 0A.

This read-only command uses block protocol with 17 bytes of data delivering IOUT results in Linear_5s_11s format.
