TMP100-EP: equivalent voltage divider on ADDx pins

Art Mecina

Part Number: TMP100-EP
Other Parts Discussed in Thread: TMP100,

Hello Guys,

Good day.

Our customer is using TMP100MDBVREP in a space application and cannot leave pins floating due to plasma charging. What equivalent voltage divider can they use on the ADDx pins to get the function of floating the pin for address assignment?

Thanks for confirmation!

Hi Art,

I am checking with our design team about requirements for an equivalent voltage divider, and I will update as soon as I have that information.

Additionally, here is a similar E2E thread regarding the TMP100 that may provide further insight. It was found that 47kΩ was the minimum required to have the float address settings available.

Best regards,

Nicole

Hi Art,

I have reached out to the design team but I believe that with the holidays coming up there may be a delay in response. In the meantime, to be able to provide them with more details, what supply is the customer planning to use with the TMP100-EP?

Best regards,

Nicole
