MFR_VOUT_MIN
This command returns the minimum ADC measured value
of the channel’s output voltage. The contents of this reg-
ister is reset to ‘hFFFF when the LTC2978 emerges from
power-on reset or when a CLEAR_FAULTS command is
executed. When odd channels are configured to measure
current, this command is not supported.
MFR_VOUT_MIN Data Contents
MFR_VIN_MIN
This command returns the minimum ADC measured value
of the input voltage. The contents of this register is reset
to ‘h7BFF when the LTC2978 emerges from power-on
reset or when a CLEAR_FAULTS command is executed.
Updates are disabled when unit is off for insufficient input
voltage.

SYMBOL
Mfr_vout_min
OPERATION
The data uses the linear format:
V(mfr_vin_min) = Y • 2
Where N = b[15:11] is a 5-bit two’s
complement integer and
Y = b[10:0] is an 11-bit two’s
complement integer
Units: V.
OPERATION
The data uses the linear mode format
as defined by VOUT_MODE:
V(mfr_vout_min) = Y • 2
Where Y = b[15:0] is an unsigned
integer and N = Vout_mode_parameter
is a 5-bit two’s complement exponent
that’s hardwired to a value of –13
decimal.
Units: V.

MFR_TEMPERATURE_MIN
This command returns the minimum ADC measured
value of junction temperature in °C as determined by the
LTC2978’s internal temperature sensor. The contents of
this register is reset to ‘h7BFF when the LTC2978 emerges
from power-on reset or when a CLEAR_FAULTS command
is executed.
