  • TPS2116: VREF Variation

    Resolved
    Part Number: TPS2116 Hello, I have a question about the characteristics of the TPS2116. The data sheet states that the VREF temperature characteristics are in the range of 0.92V to 1.08 V at -40℃ to 105℃. If the temperature range is 0℃ to 50℃, will…

  • TPS2116: Switching period

    TI Thinks Resolved
    Part Number: TPS2116 In the TPS2116 application in d/s shown, assume VIN2 is already at 5 V and fully supplying the load. When VIN1 then powers up to 5 V, the voltage on PR1 gradually rises and eventually exceeds VREF, so VOUT switches from VIN2 to VIN1…

  • TPS2116: Question about how to set the PR switching voltage

    Part Number: TPS2116 Hello, We are trying to incorporate the TPS2116 into one of our designs, and I have a question about how to set the threshold for switching between VIN1 and VIN2. From the datasheet, I understand that the MODE pin must be connected…

  • TPS2116: TPS2116 switching hysteresis information required

    Part Number: TPS2116 Tool/software: Dear TI team, I hope that you are doing well. Following is my application scenario: VIN1 = 1s 18650 Li-Ion/LiPo cell (3.2-4.2V) VIN2= 3xAA cells (4.5V) The priority will always be VIN1 through PR1 and MODE pins…

  • TPS2116: ST-pin current capability

    TI Thinks Resolved
    Part Number: TPS2116 Maybe I am overlooking something obvious, but I was not able to find the maximum current that the open-drain of pin ST can sink.

  • TPS2116: Switchover Issue

    Part Number: TPS2116 Following is my complete schematic: This board was designed to utilize a 1S LiPo as the primary source to power the load circuit ahead. When it is depleted or unavailable, it should fall back to the AA cells input without interrupting…

  • TPS2116: Output is high even when both the inputs are high

    Resolved
    Part Number: TPS2116 Hi Team, I am designing a circuit where I have a 2 common 3.3V input and my output is decided based on the priority and presense of the either of input. But I am generating the output from a 12V to 3.3V buck when both the inputs…
