Hello team,

What is the best way to terminate the DRVOFF pin in case it is unused? Open is good?

Hi Hirata san,

Thank you for your question.

DRVOFF pin has internal pull down. And DRVOFF=Low means output is turned off.

Therefore, customer need to have external pull up to keep DRVOFF pin=High (OUTPUT enabled).

Output Disabled when DRVOFF pin = High, right?

So I think open is okay, but if there is any special reason that DRVOFF cannot be open, I would like to know.

Thanks.

Hi Hirata san,

Sorry, I made wrong comment in previous post. Yes, output is disabled when DRVOFF pin=High. Customer can left DRVOFF pin open, then DRVOFF=Low and output is enabled.
