  • RE: TCA5405: Internal structure of TCA5405, PD for DIN

    TI-CSC, TI-CSC said: It's not about our system, it's about your EVB. All problems we had when we evaluated your IC on your EVB. It can switch from "a magic of hand" - you move a hand in 10cm from the PCB and it triggers ports. It's expectable for the IC…

  • RE: TCA5405: Power-up Sequencing Requirement

    Jejomar Ildefonso said: It seems doesn't have any EMI protection and it doesn't have CRC. Correct? Correct. This device wasn't designed to have built in EMI protection and it's communication protocol is a custom one which doesn't include any CRC…

  • RE: TCA5405: Output IO structure

    Hi Tsugumi, I believe we can refer to the clamp current values found in the absolute maximum ratings for the device's datasheet which reference a 20mA value. If the 10k resistor is present in your system, then you should be good enough to limit the…
