TPS51206: TPS51206 VDDQSNS iternal resistor value

Part Number: TPS51206

Hi,

We got a question from customer about TPS51206.
Could you help us?

[Question]
- How much is VDDQSNS internal resistor value?

Best Regards,
tateo

  • Hello,

    One method of determining the approximate value is to at the VDDQ Input row in Section 6.5.

    With an input voltage of 1.8V this pin consumes ~30uA. This would make the total series resistance of these two resistors ~60kohms.

    Then based on the conversation contained in the datasheet multiple places referencing VDDQSNS/2 I am assuming this is a 1/2 resistive divider.

    I hope that helps.
