VIN_UV_FAULT_RESPONSE
restart according to bits [5:3].
11 Stop regulating immediately, and then restart as soon as possible after the fault
condition abates. (Default setting)
Bits [5:3] determine the number of retry attempts. The MAX15301 supports only a subset of the full
PMBus functionality for this portion of the command:
000-110 No attempt is made to restart after a fault shutdown. (Default setting)
111 Attempt to restart continuously until commanded off, or until another fault
condition causes the unit to shut down.
Bits [2:0] determine the fault-tolerance or retry-delay timing. Each binary value in bits [2:0]
corresponds to a multiple of 100ms, up to a possible maximum of 111
bin
= 700ms. A value of 000
bin
will cause the MAX15301 to use the minimum possible timing value, typically about 30-40ms. (The
default timing for input undervoltage faults is 000
bin
.)
