READ_VIN
The READ_VIN command returns the input voltage measured between VINSNS and GND in volts.
This read-only command has two data bytes in Linear_5s_11s format.
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 V
SENSE
±
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.
