Hi,
I have question about PF3000 RESETBMCU pin behavior.
Solved! Go to Solution.
Hi Kanou,
When configured for its fault mode, RESETBMCU is de-asserted after the start-up sequence is completed only if no faults occurred during start-up. At anytime, if a fault occurs and persists for 1.8 ms typically, RESETBMCU is asserted, LOW. The PF0100 is turned off if the fault persists for more than 100 ms typically. The PWRON signal restarts the part, though if the fault persists, the sequence described above will be repeated.
All regulators (DC-DC and LDOs) are checked.
Faults:
+ Over current on all Regulators (the Over-Current Thresholds are specified for each regulator on the Electrical Characteristics Tables on the datasheet)
+ Short Circuit on all general purpose LDOs
+ Thermal thresholds
Best Regards,
Jose
