MFR_IOUT_SENSE_VOLTAGE

This command returns the absolute value of the voltage measured between ISENSEPn and ISENSEMn during the last

READ_IOUT ADC conversion without any temperature correction.

MFR_IOUT_SENSE_VOLTAGE Data Contents

BIT(S) SYMBOL

OPERATION

b[15:0] Mfr_iout_sense_voltage Absolute value of raw voltage conversion measured between ISENSEPn and ISENSEMn.

Value = Y • X • 2–13 where Y = b[15:0] is an unsigned integer and X = 0.025 or 0.75 if mfr_config_imon_sel = 0 or 1

respectively, resulting in an LSB of 3.05μV or 91.5μV.

Example:

mfr_config_imon_sel = 0

MFR_IOUT_SENSE_VOLTAGE = 1.544mV

For b[15:0] = 0x1FA = 506

Value = 506 • 0.025 • 2–13 = 1.544mV

MFR_VIN_PEAK

This command returns the maximum ADC measured value of the input voltage. This register is reset to 0x7C00

(–225) when the LTC2972 emerges from power-on reset, when a CLEAR_FAULTS command to any page is executed,

or a channel goes through an off-to-on transition.

MFR_VOUT_PEAK

This command returns the maximum ADC measured value of the channel’s output voltage. This register is reset to

0xF800 (0.0) when the LTC2972 emerges from power-on reset, when a CLEAR_FAULTS command to the page is

executed, or the channel goes through an off-to-on transition.

MFR_IOUT_PEAK

This commands returns the maximum ADC measured value of the channel’s output current. This register is reset to

0x7C00 (–225) when the LTC2972 emerges from power-on reset, when a CLEAR_FAULTS command to the page is

executed, or the channel goes through an off-to-on transition.

MFR_TEMPERATURE_1_PEAK

This command returns the maximum measured value of the external diode temperature in °C. This register is reset

to 0x7C00 (–225) when the LTC2972 emerges from power-on reset, when a CLEAR_FAULTS command to the page is

executed, or the channel goes through an off-to-on transition.

MFR_VIN_MIN

This command returns the minimum ADC measured value of the input voltage. This register is reset to 0x7BFF (ap-

proximately 225) when the LTC2972 emerges from power-on reset, when a CLEAR_FAULTS command to any page is

executed, or a channel goes through an off-to-on transition.

MFR_VOUT_MIN

This command returns the minimum ADC measured value of the channel’s output voltage. This register is reset to

0xFFFF (7.9999) when the LTC2972 emerges from power-on reset, when a CLEAR_FAULTS command to the page is

executed, or the channel goes through an off-to-on transition.
