  • TMP390: TMP390 Accuracy Question

    TI Thinks Resolved
    Part Number: TMP390 Hi TI, Regarding the TMP390A3DRLR, could you please clarify the following: Does the +-3.5K accuracy specification already account for the 1% tolerance of the setting resistors SETA and SETB? Is the temperature sensed primarily…

  • TMP390-Q1: TMP390-Q1 Sensor vs. Package Surface Temperature Behavior

    TI Thinks Resolved
    Part Number: TMP390-Q1 Other Parts Discussed in Thread: TMP390 Tool/software: Hi, We are currently evaluating the TMP390-Q1 and have observed a difference between the internal temperature sensor reading and the package surface temperature. In particular…

  • TMP390: Trigger too early

    Part Number: TMP390 Design as above, expected to be trigger at 84degC: 1) Actual testing trigger around 64degC. 2) The triggering happen on/off instead of follow the hysteresis setting. Please advise.

  • TMP390-Q1: Temperature Measurement Location

    TI Thinks Resolved
    Part Number: TMP390-Q1 Other Parts Discussed in Thread: TMP390 Hi Team, Where does TMP390-Q1 sense temperature from - die temperature, air temperature, junction temperature, etc? Thanks, Jagan

  • TMP390: Output configuration and need for pull-up resistors

    TI Thinks Resolved
    Part Number: TMP390 Tool/software: Hi, The TMP390 has two outputs (OUTA and OUTB). The data sheet specifies them as open-drain active low outputs, but there are no resistance values specified for the open state. Is it possible to connect both outputs…

  • TMP390-Q1: Do we have something with wider temp range?

    TI Thinks Resolved
    Part Number: TMP390-Q1 Tool/software: Team, My customer needs a temp switch with operating temp range -55C to 150C and I am finding nothing. TMP390-Q1 gets me close (-55C to 130C) but not quite there. Any ideas? Thanks, Brian
