TMP300: logic table - what does "trip" mean

Michael T Schneider

Part Number: TMP300

Can you confirm the operation of this part

Temperature below set point the OUT/ is HIGH

Temperature above the set point OUT/ is LOW

I don't see this in the data sheet. It only refers to a "trip" not there is no logic table to confirm if trip means low>high or high>low

Hi Michael,

Please see this previous thread which answers the question: https://e2e.ti.com/support/sensors/f/sensors-forum/717423/tmp300-tmp300-output. Also keep in mind that this part operates with a hysteresis - which is programmable to 5 or 10 degrees Celsius.

Thank you,

Chris

Chris, do we have a curve on the output voltage vs. sink current?

Michael -

The output pin of this device is not intended to be pulled up - it is intended to provide a voltage out that corresponds to the temperature, and is not intended to sink any current, nor should it be loaded. Please see figure 9 on page 9 of the datasheet. https://www.ti.com/lit/ds/symlink/tmp300.pdf
