Hello E2E support forum,
i am using TPS3514 on a board. When the board is powered up, /PSON pin is first pulled up to 5V through a 4.7kOhm resistor. 1s later, VDD pin is powered on to 5V.
When /PSON is pulled up but before Vdd is up, it seems that /PSON pin has a lower resistance (compared to when Vdd is powered up) and is drawing some current (estimated to be about 0,1mA).
I am wondering if sequence of voltage is allowed? Will there be potential problems?
Your feedback is much appreciated. Thank you.
