Part Number: TPS2121
We are using TPS2121 as a power path switch between 12V supply and 6V supply. When the voltage is 12V it should give 12V as output, which it does. But when the 12V power goes 0, the output should switch to 6V which doesn't happen in our case.
The circuit is as shown below-
Can someone help and tell what could have been going wrong?
