Other Parts Discussed in Thread: TPS65990,
I'm trying to 'or' two TPS24751 where if first one has a valid source voltage applied, the second one is shut down. I have the first one's PG# connected to EN pin of second device. After I applied a valid source voltage to first device and an open source on second device, the second device slowly burned itself up, literally with a blackened board around its VCC pin. What is the correct way to 'OR' these two? [ FYI when the TPS65990 is no longer preliminary I intend to replace just the second device. My intent is to have one USB C source and one optional wall/car adapter to run/charge my device. The output to the right feeds 50uF of ceramic caps and a BQ257503 ]
