  • RE: TPS3839: wrong positive threshold voltage

    Resolved
    The problem is solved. The connected voltageregulator generates a big inrush current which results in a voltagedrop of the inputvoltage. The inputvoltage drops below the threshold of the voltagemonitor and the monitor turns off. A capacitor at the VDD…

  • TPS3839: 850nm light seems to cause random resets

    TI Thinks Resolved
    Part Number: TPS3839 We have a design with a TPS3839 X2SON working close to a 850nm IR source. We noticed that the RESET line is randomly being pulled low when an IR LED nearby is flashing and there is a reflective surface in front of it, causing the light…
