TCAN3413: For cases where voltages are used that are outside the recommended operating range but do not exceed the maximum rating.

Part Number: TCAN3413

Hello?

I'm waiting for the release of the VSON type to change the CAN converter I'm currently developing to TCAN3413DRB. (maybe end of April?)
For the range of power (VCC) applied to this product, the maximum rating is -0.3 ~ +6.0 V and the recommended operating range is +3.0 ~ +3.6 V. (VIO=1.8 V)

If 5 V is applied to this product, how much will its lifespan be shortened?

It is indicated that there is an effect on device reliability, functionality, and performance, but I would like to know the approximate life expectancy or MTBF.

From now on, I will review whether it is possible to unify the converter into one regardless of voltage in the product I'm developing.

Thank you for reading.

    Hi S.Y.LEE,

    We've assigned this thread to one of our CAN experts who should get back to you by tomorrow.

    Thank you for your quick response.

    It would be good to be able to estimate how much it will decrease compared to the normal range.(Like -10% or 90% of the standard)
    Separately, there is a problem with my account's email system, so it is difficult to receive emails, so please answer briefly in thread.

    S.Y.,

    It is not a concern of shortening the lifespan, but rather, the driver will not be guaranteed to operate according to its electrical characteristics and switching characteristics when the recommended operating conditions are not met. The device is designed, tested, and qualified for operation with VCC between 3.0V and 3.6V. Outside of this, we cannot guarantee that the driver/receiver will operate normally.

    As long as the device is within its absolute maximum conditions, you should not expect a lifetime reduction. Instead, the concern is that operation outside the recommended operating conditions will not guarantee proper operation even at the beginning of use.

    Best,

    Danny

    The idea was to use TCAN3413 instead of TCAN1462V to support all 3.3 V and 5.0 V power applications, but I'll think about it a little more.

    TCAN3413: 

        - (VCC) Rec. 3.0~3.6 V / 6.0 V Abs. Max., (VIO) Rec. 1.7~3.6 V / 6.0 V Abs. Max.

        - D (114.4 ℃/W) / DDF (122.9 ℃/W) / DRB (50.9 ℃/W), 8-Pin Package, 8 Mbps Max., -40~165 ℃

        - Recessive output voltage normal mode: 1.9 Typ., 1.5~2.25 V

    TCAN1462V:

        - (VCC) Rec. 4.5~5.5 V / 6.0 V Abs. Max., (VIO) Rec. 1.7~5.5 V / 6.0 V Abs. Max.

        - D (120.0 ℃/W) / DDF (115.3 ℃/W) / DRB (52.8 ℃/W), 8-Pin Package, 8 Mbps Max., -40~165 ℃

        - Recessive output voltage normal mode: 0.5*VCC Typ., 2.0~3.0 V

    Thank you for review.
