TLIN1029-Q1: 起動時動作

nobuto.imahashi.uv
Prodigy 30 points
Part Number: TLIN1029-Q1
Other Parts Discussed in Thread: TLIN1029A-Q1

■質問

①電源ON直後の起動動作時は、各機能が不安定のまま使用すると誤動作・誤検知リスクがあるため、

その対象となる部位・期間に対し、誤検知させないためのふるまいが確認されているでしょうか？

②上記で保護されている上で、起動直後にトリミング切替回路等による不安定期間が発生しうるか、

不安定期間がある場合は誤検知しないようにケアされているでしょうか？

 

③発生する場合の懸案事項や制約事項に関して、データシートへの記載はあるでしょうか。

    Imahashi-san,

    Unfortunately I am not fully sure I know what you're asking here, so please pardon me if I misunderstand.

    First, please consider the TLIN1029A-Q1 instead of the TLIN1029-Q1 as the TLIN1029A-Q1 is the newer component.

    For this component, the timing characteristics are given in the Timing Requirements section (section 7.8) of the data sheet. Here, there is a timing characteristic called tPWR, which is the amount of time it takes after power-up for the data on RXD to be considered valid. This could be used as a timing for your microcontroller to wait after power-on to ignore LIN data before communicating.

    If you're having another issue that I've misunderstood, please feel free to share additional details here so that we can try and assist.

    Best,

    Danny

    Hello Nobu,

    Let me asnwer your query below.

    1) Our TLIN device doesn’t have unstable point when just after power on.
    This is verified during characterization prior to product release.

    2) & 3) N/A due to above reason.

    Regards,
    ti
