TIC10024-Q1: Battery supply range - 18 V for 1 hour ISO 16750-2

Part Number: TIC10024-Q1
Other Parts Discussed in Thread: TIC12400-Q1

Hello,

I am planning to use the TIC10024-Q1 in an automotive ECU.

Since, as stated in the datasheet, the TIC10024-Q1 is designed and tested according to the ISO 16750-2: can I assume that it supports all the tests from the ISO although they are not mentioned in the datasheet?

In particular, the ISO defines a test at 18 V supply voltage for 1 hour, which is not explicitly mentioned in the datasheet. Is this test supported?

Thank you in advance,

Luca

    Hi Luca,

    In addition to specifically stating that "It shall be noted that the TIC10024-Q1 is designed and tested according to the ISO 16750-2 standard." The datasheet mentions "±8 kV Contact discharge ESD protection on input pins per ISO-10605 with appropriate external components."

    I would assume that the device was only tested to the ISO16750-2 standard and the ISO-10605 standard, but not all ISO standards.

    Regards, Amy

    Hi Amy,

    Thank you for your answer. I am afraid my question was not clear.

    What I am trying to confirm is if TIC10024-Q1 is tested with all the tests defined in the ISO 16750-2, including the tests not mentioned in the datasheet.

    The test I am most interested in is the 18 V for 1h test, which is part of the ISO 16750-2. I assume the TIC10024-Q1 does support it, but I want to make sure since it is stated the IC supports nominal operating voltage up to 16 V.

    Regards

    Hi Luca,

    I noticed in the datasheet that after the statement of "It shall be noted that the TIC12400-Q1 is designed and tested according to the ISO 16750-2 standard." it mentions that "A few voltage stress tests and their test conditions are listed below" - I take this to mean that that datasheet is not all inclusive of ISO 16750-2 tests run, but the device was tested by the ISO 16750-2 standards. The TIC10024-Q1 contains a supplemental application note "Protecting 12-V MSDI Devices in a 24-V System" that contains further detail of the ISO 16750-2 load dump test: Protecting 12-V MSDI Devices in a 24-V System. If you need more details, I can check into this further and see what I find.

    Regards, Amy

    Hi Amy,

    Thank you for your feedback.

    To summarize it appears that the TIC10024-Q1 is ISO 16750-2 compliant and that it may be used in 24 V systems respecting certain conditions.

    Regards, Luca
