Hi,
My board has 2 usb 5V inputs.(1 from USB port and another from USB wall Charger)
I plan use USB port to power my board for most of the time and use charger as a back up if more current is needed.
The auto selecting mode seems to be well suited for my application.
I want to understand a bit more about how it works in the following situation .
1) The load is drawing more than 500mA and input A dip below certain voltage. It switches to input B
At this time The input goes back to 5V. Which voltage will the switch pick since they are both 5V.
2) if only the USB port is present and the voltage dip below the threshold.
what will the switch do. will it turn off the circuit? and wait until USB port back to 5v again and then it repeats?
2) The data sheet say that "circuit will connect N1 to output until N1 dip below a user defined voltage".
I could not find any information regarding how to define the voltage threshold.
how do i define threshold voltage to be 4V to switch to port B.
Thanks,
Eddy
