  • RE: TPS25981: After overcurrent >2x ILIM / short circuit (=Fast trip) the device tries to switch on after 30µs even if we have the latch function

    Hi Andreas, The device will perform this restart after FFT with 30us delay by design. This is present to ensure any issue like false transients don't cause system down. In your use case, it looks like the FFT is happening and afterwards the device is…

  • RE: TPS25981: PG signal troubleshooting

    Hi Alberto, Can you share the layout screenshot (all layers) or files. I only need to check the eFuse part of it. There might be some issue in the layout. Can you add some external input capacitance and just check if it is helping? It should be a quick…

  • RE: TPS25981: high inrush current

    Hi Jeff, I apologies for the delayed response. Did you get any solution? TPS25981 device have both scalable Fast Trip (SFT) and Fixed Fast Trip (FFT). FFT threshold is 39.5A and SFT is 2*ILIM. Can you confirm, the device is not triggering the circuit…

  • TPS25981: TPS259814LRPW UVLO

    TI Thinks Resolved
    Part Number: TPS25981 Team, Is the UVLO a permanent fault? I believe it is as it's the latch version. Customer wants the system to be done ideally. The TPS25981xx implements undervoltage protection on IN in case the applied voltage becomes too low…

  • TPS25981: Parallel Configuration

    TI Thinks Resolved
    Part Number: TPS25981 Hello, TPS25981's data sheet has a picture of two TPS25981s' parallel configuration in Figure 9-2 on page 32, and a TPS25981's PG output goes to the other one's EN/UVLO input. A simulation result of this configuration shows a glitch…

  • TPS25981: EN control of TPS259814A after overload removal

    Resolved
    Part Number: TPS25981 I am checking the overcurrent protection operation of my prototype board with TPS259814A. After the overcurrent protection works, the TPS259814A automatically returns to steady state when the load is removed. However, after that, OUT…
