TUSB216I: Test Condition of IACTIVE_ HS and IIDLE_HS

Shinichi Inoue
Guru 19931 points
Part Number: TUSB216I

Dear Specialists,

My customer is considering TUSB216I and has questions.

I would be grateful if you could advise.

---

Regarding Datasheet P.6 6.5 About IACTIVE_HS and IIDLE_HS in Electrical Characteristics

(1) Boost Max means DC_Boost_Register 0xF or BOOST PIN LEVEL 3?

(2) RX_SEN setting is not described in the test conditions.
Is it correct to assume that RX_SEN = LOW?

How much does the current consumption increase when RX_SEN = High?

(3) What other functions consume a large amount of current?

---

I appreciate your great help in advance.

Best regards,

Shinichi

    Hi Shinichi,

    1.) Boost Max means Boost Level 3.

    2.) RX_SEN is at high during testing.

    3.) No other functionality on the device should consume a large amount of current.

    Please let me know if you have any other questions.

    Thanks,

    Ryan

    Hi Ryan,

    Thank you for your reply.

    I understood the IACTIVE_HS includes Boost Level3 and RX_SEN High.

    When IACTIVE_HS current consumption is 22mA typ, what is the ratio between Boost Level 3 and RX_SEN High?

    I'd like to know which current is larger.

    If possible, could you please provide the current consumption data for each level of Boost Level3 and RX_SEN High?

    I appreciate your great help and cooperation.

    Best regards,

    Shinichi

    Hi Shinichi,

    Unfortunately, I am not able to share that kind of information, it is proprietary to TI. Sorry about that.

    Please let me know if there are any other questions I can try to answer.

    Thanks,

    Ryan

    Hi Ryan,

    Thank you for your reply.

    I understand there is no data for current budget between Boost and RX_SEN.

    I'll share this information with the customer and make them confirm by themselves.

    When they have an additional question, I consult you again,

    I appreciate your great help and cooperation.

    Best regards,

    Shinichi
