PMBus Command Description
MFR_VINEN_UV_FAULT_RESPONSE
This command register determines whether VOUT undervoltage faults from a given channel cause the VIN_EN pin to be
pulled low.

0 = Do not disable VIN_EN.
Response to channel 1 VOUT_UV_FAULT.
b[0] Mfr_vinen_uv_fault_response_chan0
1 = Disable (pull low) VIN_EN via fast pull-down.
0 = Do not disable VIN_EN.
Response to channel 0 VOUT_UV_FAULT.
1 = Disable (pull low) VIN_EN via fast pull-down.
0 = Do not disable VIN_EN.
MFR_RETRY_DELAY
This command determines the retry interval when the LTC2978A is in retry mode in response to a fault condition. The read
value of this command always returns what was last written and does not reflect internal limiting.
MFR_RETRY_DELAY Data Contents
BIT(S) SYMBOL
OPERATION
b[15:0] Mfr_retry_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.
