TPLD1201-Q1: Temp Sensor Aggregator with Alert

David Shumate

Part Number: TPLD1201-Q1
Other Parts Discussed in Thread: TMP61, TPLD2001, TPLD1201

Hi Team,

I would like to see if it would be feasible to utilze the TPLD1201-Q1 as a temperature sensor aggregator with a single altert output.

In this usecase I would take 6xTMP61-Q1 devices and feed them into GPIOs of the TPLD device. If any of the TMP61 devices rise to a high enough voltage to indicate that it is >120 degrees I would like a output GPIO to go high as an alert function.

Let me know if you think this usecase is feasible with TPLD

Thanks,

David

    Hi,

    Today is an American holiday, so responses will be delayed. I'll get back to you on Monday.

    Hi David,

    Thanks for your patience. 

    This seems like a great use of TPLD. However, TPLD1201 only has two analog comparator , and it sounds like you need 6. Is that correct? In that case, I think you should be looking at TPLD2001 which has a total of 8 voltage comparators. If you give me more information, I can help you with the design.

    Regards,

    Nikki
