TCAN1043-Q1: Low power fault protected

Part Number: TCAN1043-Q1


Hi team,

I have some questions about 'low power fault protected' meaning.

1. Could you explain some detail about 'low power fault protected'? Is it for sleep mode and stand by mode?

2. Could you explain relation with each function such as remote wake up, INH and low power fault protection?

Thank you.

Best Regards,

Kevin Shin

    Kevin,

    1. "Low-power fault protect" is referring to the transceiver's features of being able to go into low-power mode, and having fault protection features in all modes. Low-power and fault protected were meant to be two separate descriptors of the transceiver. Low-power is referring to the device have sleep and standby mode for low-power consumption, and fault protected is referring to the CAN bus pins have absolute maximum voltage rating up to 58V and 70V on the H version.
    2. Remote wake-up is referring to the CAN bus wake-up so they device can transition from sleep to standby mode, and INH is the pull-up to battery that is enabled when the device is in standby or sleep mode, typically meant to enable the power supply for VCC and/or VIO. Low power and fault protection were meant to be separate and just refer to the fact that sleep and standby mode are available, and that the CAN bus pins are protected against high-voltage faults (short to battery during a load dump).

    Please let me know if you have any other questions.

    Regards,
