TMP390: Value of Rset in TMP390

Part Number: TMP390

Hi team,

Customer were using TMP390 in their latest project.We were facing a question: for example: as table1 shown, Rset were recommended to 442kohm, but we only can choose the 470kohm or 430kohm. what influence would cause?  whether the value of Rset with temperture was linear?



  • Hi Brandon,

    442 kohm is a standard E-96 resistor value.  What is the reason the customer can only use the non E-96 standard value resistors?  Without using using the specified resistor value and tolerance we cannot guarantee that the device will set the trip point correctly.
