As per page 56 of the datasheet pasted below, if not sequenced ideally,
- Are the undesired power currents damaging to the device? What sort of level are they likely to be?
- What are the consequence of an error in sequencing?
- Are the same consequences likely on erroneous power-down sequence (in case of fault on a rail etc)?
We can use PG's and Track pins on DC-DC but would like to understand the consequences. If the undesired power currents flow for a while are there thermal implications? Parasitic diode between rail failures possible etc?
Also - if used in RX mode only, what are the needs for the 1V8 supplies on VDDA_IF and VDDA_1P8.
It looks like VDDA_1P8 is not needed if there is no TX used?
