TMP411: TMP411ADR: Holds the SDA line low

H Jayaraj
Intellectual 470 points
Part Number: TMP411

Tool/software:

I am seeing a leakage on the power supply of temperature sensor, and I know from my initial debugging that the leakage is by some other device. That leakage is up to 0.95V. But my temperature sensor holds the SDA line low whenever it sees a 0.95V in its V+ pin. I am not seeing any details on datasheet which can relate to this issue. Please help understand this.

    Hello Harsh,

    What exactly are you seeing in regards to leakage in the power supply? Can you provide scope shot of what you are seeing? What lot code did you packaging come in? This information can be found on the sticker on the packaging. What markings are you seeing with this device?

    Best Regards,
