Part Number: TCAN1463-Q1

Hi, Support Team


We want to replace TJA1463, but some Electrical Characteristics didn't see in datasheet.

Please help to check.

2. Standby mode current w/ VIO (max)  ?

3. WUP Filter time (Long & Short)         ?

4. VeLIO Compliance ?

    Hi Lawrence,

    Thanks for checking in. Our device specifies worst-case maximum supply current in standby mode as 60 μA in standby mode (ISUP_STBY), and I/O supply current as up to 5 μA in standby mode (IIO_NORMAL).

    Our wake-up filter time is given as 0.5 μs - 1.8 μs (tWK(FILTER)) for a filtered dominant and/or filtered recessive signal. The WUP must be received within 0.8 ms - 2.0 ms (tWK(TIMEOUT)).

    TI works closely with Toyota conformance testing (VeLIO). The device is still in VeLIO testing but is expected to pass, though its results have not yet been published.

    Best,

    Danny

    Hi, Danny

    let me double confirm, so your mean is

    1.Standby mode current w/o VIO (max) is 60uA

    2,Standby mode current w/ VIO (max) is 5uA

    is correct?

    By the way TCAN1463-Q1 could possible to approvide AEC-Q100 Grade-0?

    if any, Please advise me.

    Thanks,

    Best regards,

    Lawrence

    Lawrence,

    Sorry for any confusion - the I/O current is in addition to the standby current, so these numbers would be added together in theory when VIO is applied. The total current consumption wouldn't usually ever reach this level since these are both worst-case maximum values, but it would be the number you're looking for I believe.

    AEC Grade 0 rating is based upon ambient temperature of -40C to +150C. TI's device is spec'd to a junction temperature that meets this range, but the device is Grade 1 based upon ambient temperature. Junction temperature is a better metric of device temperature resilience, since the actual temperature of the device depends on many factors, including power consumption, ambient convection, and heat dissipation through the board, so this is why TI has moved toward using junction temperature instead of an estimate of ambient temperature.

    Best,

    Danny
