Slot[A/B] Fault Reporting
The MIC2341s /FAULT_MAIN[A/B] open-drain digital
output are activated after power-on-reset and become
asserted when:
The ON[A/B] input signals are asserted, AND
" The 12VIN[A/B] or the 3VIN[A/B] input
voltages is less than its respective ULVO
threshold, OR
" The fast OC circuit breaker[A/B] has tripped,
OR
" The slow OC circuit breaker[A/B] has tripped
AND its corresponding C
FILTER[A/B]
timeout or
the digital filter delay has expired.
In order to clear the /FAULT_MAIN[A/B] outputs once
asserted and to reset the corresponding circuit
breaker(s), a high-to-low transition is required on the
ON[A/B] input signals. Please see /FAULT_MAIN[A/B]
pin descriptions for additional information.
Figure 10. State Diagram for /FAULT_MAIN[A/B] Signals
The MIC2341s /FAULT_AUX[A/B] open-drain digital
outputs are activated after power-on-reset and become
asserted when:
The AUXEN[A/B] input signals are asserted, AND
" The slow VAUX[A/B] OC circuit breaker has
tripped AND its corresponding C
FILTER[A/B]
timeout or the digital filter delay has expired,
OR
" The slow VAUX[A/B] OC circuit breaker has
tripped AND the Slot[A/B] die temperature is
higher than 140癈, OR
" The MIC2341s global die temperature is
higher than 160癈
In order to clear the /FAULT_AUX[A/B] outputs once
asserted and to reset the VAUX[A/B] circuit breaker(s), a
high-to-low transition is required on the AUXEN[A/B]
input signals. Please see /FAULT_AUX[A/B] pin
descriptions for additional information.
If the /FORCE_ON[A/B] digital inputs are used for
diagnostic purposes, the /FAULT_MAIN[A/B],
/FAULT_AUX[A/B],
/PWRGD[A/B],
and
/DLY_PWRGD[A/B] digital outputs are de-asserted once
/FORCE_ON[A/B] inputs are asserted.
