DS90UB914A - value of internal pulldown

Genius 4905 points

Hi,

Can you help me to figure out the PDB pin's internal pull-down resistor value of DS90UB914A?

Thanks for your reply in advance.

Regards,

Nao

  • Hello Nao,

    I believe previous E2E questions have answered this question, but I will answer here as well. The internal pulldowns on pins inside our device are not a discrete resistor but instead an active resistance based upon internal transistor. This active resistance will vary depending upon width of pin's internal transistor, temperature, etc. 

    The pulldown value for this pin is weak and approximately 100kOhms under nominal/typical use-case.
