Hi team,

How much does it take time from the temperature reaches the threshold temp to OT pin goes low?

Hi Takahashi-san,

Thank you for posting to the Sensing forum.

We don't have thermal response data for the TMP709, but I would expect it to be similar to Figure 11 of the TMP235 datasheet.

Best regards,

Nicole

Nicole,

Thanks, but my question is not the thermal response. I want to confirm the time for OT pin to go low after the thermal reach the certain threshold.

Regards,

Hi Takahashi-san,

Since the TMP709 is an analog switch it is designed to have an instantaneous response, and there is no intentional delay before the OT pin is asserted.

Best regards,
