I have the circuit as in attached image.
It will auto detect the input power rail VPWR ( 12V or 5V ).
If the input power rail is 12V, the VPWR_SEL will be “high” otherwise VPWR_SEL will be low.
My co-worker keep bothering me for long time for this circuit.
Do you thank it will work properly as what I want ?
Very appreciate for your suggestions.
