pin transitions whose OFF time exceeds Mfr_restart_delay are not affected by this command. A value of all zeros disables
thisfeature.
MFR_RESTART_DELAY Data Contents
BIT(S) SYMBOL
b[1ꢀ:±] Mfr_restart_delay The data uses the L11 format.
This delay is counted using SHARE_CLK only.
OPERATION
Delays are rounded to the nearest 2±±µs.
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 sup-
ported for odd channels that are configured to measure current. This register is reset to ±xF8±± (±.±) 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[1ꢀ:±] Mfr_vout_peak[1ꢀ:±] The data uses the L16 format.
Units: V.
MFR_VIN_PEAK
2ꢀ
This command returns the maximum ADC measured value of the input voltage. This register is reset to ±x7C±± (–2 )
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[1ꢀ:±] Mfr_vin_peak[1ꢀ:±] 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
2ꢀ
internal temperature sensor. This register is reset to ±x7C±± (–2 ) 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[1ꢀ:±] Mfr_temperature_peak[1ꢀ:±] The data uses the L11 format.
Units: °C.
