TCAN1044V-Q1: 起動時動作

Part Number: TCAN1044V-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。

    Hi Imahashi-san,

    Sorry this is an English forum so I might not understand your question correctly. What kind of fault/error did you meet during powerup? Can you provide a capture of waveform that indicating any fault on the bus during the startup.

    If there is a signal integrity/stability issue please also share us the schematic.

    Regards,

    Sean

    Hello Nobu,

    Let me asnwer your query below.

    1) Our TCAN 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
