TMP401: Schematic check about TMP401 based design

Part Number: TMP401

Hi team,

My customer is planning to using TMP401 as thermal sensor in the design. 

Below is a rough schematic, Could you help to review and confirm whether the design is OK please?

Thank you

Max

  • Hi Max,

    Two comments. 

    1. Since the supply voltage is only at 3.3 V the max series resistance is only 500 Ω (this is the sum of both resistors from the BJT).  

    2. I assume there are pull-up resistors on the I2C pins on a different part of the schematic.  If not, theyneed to be added.  

    Thanks,

    David
