TPS3840: The resistor values of Vdd

R.Fukunaga
Expert 2505 points
Part Number: TPS3840

Tool/software:

Hi all,

I would like to ask about the multiplier of the external voltage divider.

The datasheet says, 

”The resistor values must not be so large that the external resistor divider affects the accuracy or operation of the device.”

Is there recommended value?

My customer considers between 1kΩ to 10kΩ

Best Regards,

Ryusuke

    Hi Fukunaga-san, 

    Thanks for sharing your customer requirement. 1k-10k should be good. If they need low Iq they can go up to 100k Ohm range. I think Mohms range is the range the datasheet is highlighting.  

    Thanks,

    Sila
