TPS4H160-Q1: About thermal shutdown and more information

Part Number: TPS4H160-Q1

Hello to whom it may concern,

We have some question about TPS4H160-Q1.

Q1,
  We are going to use THER pin is "H".
  Is there a diagram that is explained in more detail than Figure31 about THER=H?
  We would like to know more detail about thermal shutdown, when THER is H.

Q2,
  Are there IPD products with Hiccup Mode function?
  We can't found IPD products with Hiccup Mode.

Best regards,

    Hello,

    When the THER pin is high and junction temperature hits the shutdown threshold, the output latch off. Are you asking about the thermal swing between FET and logic temperature difference when the THER is high?

    TPS1H000 has the Hiccup mode.

    Regards,

    Hi Harmouch-san

    Thanks for your quick replay.

    > When the THER pin is high and junction temperature hits the shutdown threshold, the output latch off.
    Are you asking about the thermal swing between FET and logic temperature difference when the THER is high?

    --> We will ask you a question once again after confirming a little more.

    > TPS1H000 has the Hiccup mode.

    --> Thanks for your good information!
    However I have question.
    Are there plans to develop multi-channel IPD with Hiccup mode?
    Why is TPS1H000 cheaper than TPS1H100?
    Are there structural improvements?

    Best regards,
