Part Number: TLIN1028-Q1

Hello team,

My customer would like to know two kind of time as shown in below. 

  1. Transition time to Normal mode from at the time Vsup>Vsup(min)=5.5V. EN=always high.
  2. Time to data output at LIN bus from data receive at TxD pin.

Regards,

Youhei MIYAOKA

    Miyaoka-san,

    If you look in the datasheet timing characteristics, the maximum time for powerup initialization is 2ms, and the maximum time for normal mode initialization to receive data is 35us. So, for the customer to guarantee the SBC is ready after powerup to receive data is 2ms + 35us. Please let us know if you have any other questions.

    Regards,

    Hello Eric,

    Thanks! How about #2 question? > Time to data output at LIN bus from data receive at TxD pin.

    Hi Youhei,

    Unfortunately, the data sheet do not seem to specify a dedicated TXD to LIN propagation delay parameter. However, the transmitter delay should already be included within the LIN physical layer timing compliance, thanks. 

    Best Regards,

    Michael.
