Power Path Selector with STMPS2141STR

Hello everyone,

I am designing a PCB and I want a power path selector which can change the source between USB and Battery.

Can I do this with STMPS2141STR ?

I cannot find a circuit or an application note.

This is my design is that correct ? Can somebody explain to me please

Hello @testbenchmark,

If I understand, you want to supply with de battery trough a 5V regulator, and switch to USB only if there is no battery?

If I am right your schematic should work.
