TMP110: TMP110Dx

Part Number: TMP110

Tool/software:

H all.

i would like to use temperature sensors item TMP110Dx, i will use the nominal requested power in the data sheet which is 3.3v.

the output alert pin is an open drain, can i connect it to a different voltage rail, let say for example to 1.8v?, it should work since this is an open drain output, but to be sure, do you see any problem/issue with this, can the open drain be connected to a lower voltage then the sensor itself (3.3v) ?  

thx.

Nitsan.

  • Hello Nitsan,

    If the line connected to the ALERT pin is powered with a different rail, that shouldn't be a problem. Just ensure the appropriate pull-up resistor is placed on that line.
