  • RE: TPS274160: There is a chance that PWMing the device will trigger FAULT pin

    Resolved
    Hi Weiwei, Thank you for providing those waveforms! I would be additionally curious to see the VOUT waveform overlaid by the ST plot and zoomed in. Since EN is low when ST is pulled low, the condition which is triggering ST low would have to be open load…

  • TPS274160: Questions regarding toggling of EN and DIAG_EN

    TI Thinks Resolved
    Part Number: TPS274160 We are considering an application for TPS274160. For the sake of argument, let's consider only using 1CH (the other 3CH are disabled); in this case: 1) Let's assume DIAG_EN = 5V // EN = 0V // xST = LOW (reporting open-load fault…
