READ_IOUT

The READ_IOUT command returns the average output

current in amperes. The LTC7131-1 senses and measures

the currents through its bottom power switches to derive

IOUT current. For accurate values at light load currents the

part must be in continuous conduction mode.

This register is reset to 0x8000 is standby mode when

the drivers are off.

This read-only command has two data bytes and is for-

matted as a 16-bit 2’s complement value scaled 10mA/bit.

READ_TEMPERATURE_1

The READ_TEMPERATURE_1 command returns the inter-

nal die temperature, in degrees Celsius, of the LTC7131-1.

This read-only command has two data bytes and is for-

matted as a 16-bit 2’s complement value scaled 1°C/bit.

MFR_VOUT_PEAK

The MFR_VOUT_PEAK command reports the highest volt-

age, in volts, reported by the READ_VOUT measurement.

To clear the peak value and restart the peak monitor, use

the MFR_CLEAR_PEAKS command or write to the MFR_

VOUT_PEAK. When writing to MFR_VOUT_PEAK, zero,

one or two data bytes are accepted but the data is ignored.

This command has two data bytes and is formatted as a

16-bit 2’s complement value scaled 0.5mV/bit.

MFR_VIN_PEAK

The MFR_VIN_PEAK command reports the highest volt-

age, in volts, reported by the READ_VIN measurement.

To clear the peak value and restart the peak monitor, use

the MFR_CLEAR_PEAKS command or write to the MFR_

VIN_PEAK. When writing to MFR_VIN_PEAK zero, one

or two data bytes are accepted but the data is ignored.

This command has two data bytes and is formatted as a

16-bit 2’s complement value scaled 4mV/bit.

PMBus COMMAND DETAILS

MFR_TEMPERATURE_1_PEAK

The MFR_TEMPERATURE_1_PEAK command reports the

highest temperature, in degrees Celsius, reported by the

READ_TEMPERATURE_1 measurement.

To clear the peak value and restart the peak monitor,

use the MFR_CLEAR_PEAKS command or write to the

MFR_TEMPERATURE_1_PEAK. When writing to MFR_

TEMPERATURE_1__PEAK zero, one or two data bytes

are accepted but the data is ignored.

This command has two data bytes and is formatted as a

16-bit 2’s complement value scaled 1°C/bit.

MFR_IOUT_PEAK

The MFR_IOUT_PEAK command reports the high-

est current, in amperes, reported by the READ_IOUT

measurement.

To clear the peak value and restart the peak monitor, use

the MFR_CLEAR_PEAKS command or write to the MFR_

IOUT_PEAK. When writing to MFR_IOUT_PEAK, zero, one

or two data bytes are accepted but the data is ignored.

This command has two data bytes and is formatted as a

16-bit 2’s complement value scaled 10mA/bit.

MFR_IIN_PEAK

The MFR_IIN_PEAK command reports the highest cur-

rent, in amperes, reported by the READ_IIN measurement.

To clear the peak value and restart the peak monitor, use

the MFR_CLEAR_PEAKS command or write to the MFR_

IIN_PEAK. When writing to MFR_IIN_PEAK, zero, one or

two data bytes are accepted but the data is ignored.

This command has two data bytes and is formatted as a

16-bit 2’s complement value scaled 10mA/bit.
