Product Number: LTM4644
Can the LTM4644 control the power-on sequence by cascading the PGOOD and RUN pins?
In addition, does this solution have any other problems besides not being able to control the power-off sequence?
The technical document (Care and Feeding of FPGA Power Supplies: A How and Why Guide to Success | Analog Devices)says: this scheme cannot gracefully handle faults or manage energy in uncertain operating conditions. Can you give an example of a specific failure mode?
In addition, if there is a large temperature change, is this method of controlling the power-on sequence reliable? If not, can you explain the reason in detail?
