Other Parts Discussed in Thread: TPS73801, TPS7A7001

Hi

My customer has question.Please cooperate.

It is written as "Connect to Vin if not being used"the TPS7A7001/TPS73801 datasheet.

 Therefore, Not equipped with such pull-down resistance at the time of the indefinite voltage in the Device?

Or has a pull-down resistance to internal?

Best Regard

    Hi T Kishi,

    I believe you are referring to the EN pin with your question. Please let me know if this is not correct.

    EN is looking for a logic high or a logic low. If your application does not require EN to be sequenced separately from IN, then connecting EN to IN allows for the proper logic level on EN without requiring any further components.

    For future posts it will help if you post separately for each device. In this case the answer is the same for both devices, but this is not always the case.

    Very Respectfully,
    Ryan

    Hi Ryan

    Thank you for reply.Sorry,It was a EN pin of the question.

    In other words, the appropriate Enable To Low,

    it is necessary to put a pull-down resistor to the external?

    Best Regard

    Hi T Kishi,

    Enable should be driven either high or low at all times and not left floating.  A pull-down resistor is not required.

    Very Respectfully,
