TMP117: ALERT pin state before the end of the first conversion

Tristan REIMANN

Part Number: TMP117

Dear Sir,

We would like to know what would be the state of the ALERT pin between the power-on and the first conversion result and if it is dependent of registers?

Best regards,

Tristan

Hi Tristan,

The alert pin is an open drain interface so as long as you have a pullup resistor, the line will be high. There are a few ways in which you can configure alert through the configuration register such as polarity and mode--the default (POR value) being active low and alert mode.

Best regards,

Hi Simon,

Thanks for your feedback, we have build the power-on sequence diagram in Therm mode based on your feedback, could you please confirm it, in particular ALERT pin on sequence 1 and 2 below?

Best regards,

Tristan
