TPS3705: Can PFI leave float?

Jeff Xie

Part Number: TPS3705

Hi team,

Customer use TPS3705 as watchdog, below is the schematic. What should PFI and PFO be treated if I did not use it?

Can I leave them float?

If Power-Failure Input/Output is not used, they can both be left floating, as they have no impact on the RESET logic.
