Part Number: TPS2115A

Hello,

            if IN1/IN2 voltage one of them are 0V or floating, TPS2115A still work normal to switching input voltage to output? Thank you.

    Hi Patrick,

    Yes, the TPS2115A will still work as long as one of the supplies is greater than 2.8V. For example, if IN1=5V and IN2 is disconnected, then the part will still be able to pass IN1 to the output. It is not recommended to switch to the disconnected (or 0V) supply to power the output.

    Thanks,
