TLIN2029A-Q1: 48V system question

Taku Murayama
Intellectual 1830 points
Part Number: TLIN2029A-Q1

Tool/software:

Hi,

①What are the meanings of a commander and a responder? Will the commander become the master and the responder become the slave?

②If it becomes a 48V system, will the bus voltage of LIN also be TYP48V?

③recommended Operating Conditions
The TLIN2021A is MAX.45V and the TLIN2029A is MAX.48V.
Is this because the Tj condition differs from 2021:MAX.150°C and 2029:MAX125°C?

④ What in system configuration is Wake-up used with the wake terminal?

BR,

Taku

    Hi Taku,

    1. Yes, this is the updated terminology as commander controls communication sending commands on the network while responder listens to commands and responds with the requested information.

    2. No, the device can tolerate 48 V during fault conditions but LIN typically operates in 12 V to 24 V for automotive systems.

    3. No, they are just designed differently to handle slightly lower fault tolerance.

    4.Used to wake up the device from sleep mode or low power mode in the LIN network. EN pin receives a wake-up signal and awakens from sleep mode for normal communication. WAKE terminal is active low and when the bus sends wake-up signal, the device becomes active for normal communication similar to 7.4.4 of the data sheet, thanks.

    Best Regards,

    Michael.
