LTC2978
PMBus Command Description
MFR_RESTART_DELAY
This command sets the minimum off time of a CONTROL initiated restart. If the CONTROL pin is toggled off for at least 10µs
then on, all dependent channels are disabled, held off for a time = Mfr_restart_delay, then sequenced back on. CONTROLn
pin transitions whose OFF time exceeds Mfr_restart_delay are not affected by this command. A value of all zeros disables
this feature.
MFR_RESTART_DELAY Data Contents
BIT(S) SYMBOL
OPERATION
b[15:0] Mfr_restart_delay The data uses the L11 format.
This delay is counted using SHARE_CLK only.
Delays are rounded to the nearest 200µs.
Units: ms. Max delay is 13.1 sec.
MFR_VOUT_PEAK
This command returns the maximum ADC measured value of the channel’s output voltage. This command is not
supported for odd channels that are configured to measure current. This register is reset to 0xF800 (0.0) when the
LTC2978 emerges from power-on reset or when a CLEAR_FAULTS command is executed.
MFR_VOUT_PEAK Data Contents
BIT(S) SYMBOL
OPERATION
b[15:0] Mfr_vout_peak[15:0] The data uses the L16 format.
Units: V.
MFR_VIN_PEAK
This command returns the maximum ADC measured value of the input voltage. This register is reset to 0x7C00 (–225)
when the LTC2978 emerges from power-on reset or when a CLEAR_FAULTS command is executed.
MFR_VIN_PEAK Data Contents
BIT(S) SYMBOL
OPERATION
b[15:0] Mfr_vin_peak[15:0] The data uses the L11 format.
Units: V
MFR_TEMPERATURE_PEAK
This command returns the maximum ADC measured value of junction temperature in °C as determined by the LTC2978’s
internal temperature sensor. This register is reset to 0x7C00 (–225) when the LTC2978 emerges from power-on reset
or when a CLEAR_FAULTS command is executed.
MFR_TEMPERATURE_PEAK Data Contents
BIT(S) SYMBOL
OPERATION
b[15:0] Mfr_temperature_peak[15:0] The data uses the L11 format.
Units: °C.
