TMP431: application note apply in measuring Thermal diode of ATE machine test application scenario

Daoyan Zhao
Expert 3535 points
Part Number: TMP431

Tool/software:

Hi Expert,

May I know if TMP431 can be used to measure Thermal diode(Synopsys) of die in ATE machine test, should TMP431 be integrated in test PCB of ATE Tester? Do we have some application note to introduce this kind of use case? If you have any other proper device recommended, pls feel free to let me know. Many thanks!

BR,

    Hi Daoyan,

    This will depend on the beta compensation and n-factor correction for this diode. If this is something that is unknown, it would need to be characterized to see if TMP431 is compatible. Have you characterized or simulated the response of the internal thermal diode? Do you know what the response accross temperature should be? Let's follow up on this over email.

    Best regards,
