TPS2116: Schematic review (TPS2116 - Manual mode)

Part Number: TPS2116

Hi,

I am planning to use TPS2116 as a power selector switch (Manual mode). Can you verify the below schematics? Do i need a pull up at the PR1 pin?

  • Hi Sowmiya, 

    Based on your schematic, by pulling mode high (>1V), PR1 will decide which valid input (≥1.6V) is outputted. 

    This PR1 signal is compared against an internal Vref value to determine if the PR1 signal is high or low. 

    Please ensure your GPIO_PR1 signal is never floating to ensure known operation. 

    Best Regards, 

    Elizabeth
