Tool/software:
Hi,
Using TPS2121 chip for dual power switching, the following issues were found, please help analyze.
1. At the 12V end, using a switch (soft switch or hard switch) for control will result in a 5V power outage reset restart when the 12V is turned off.
2. If the 12V plug is directly plugged in and out, it will not reset when unplugged, but there is a probability of power failure reset when plugged in.
