PLEASE HELP!!! HMC939ALP4E is damaged when was turned on.

What is the recommended power supply startup sequence?

What happens if -5B is lost? or What happens if +5B is lost? or What happens if GND is lost?

In all cases after the chip is damaged, the current in the -5V circuit is greater than 5 mA (25-100 mA).

There are more than 10 such cases !!!
