AD5682R Power -On Reset

Hello All,

 

I have some questions for AD5682R Power-On Reset.

Looks like datasheet does not state the details…

 

Q1) What is the threshold voltage value for POR?

And which pin’s voltage level does monitor for? VDD and or VLOGIC?

(Please see the attached picture for your reference)

 

Q2) What’s the POR behavior at the time when the voltage is falling down such as the temporary blackout?

 

Best Regards,

  • Hi Takashi-san,

    Apologies for the delay. The POR Trip Level is less than VDD min though I am not sure of the exact value. I will get back to you on this. If the supply returns to the operating range without reaching the POR value, the part should still be okay.

    I am looking for more details so I will get back to you as soon as possible.

    Regards,
