  • TMP61-Q1: How to change the Rbias in the Thermistor Design Tool

    TI Thinks Resolved
    Part Number: TMP61-Q1 Other Parts Discussed in Thread: TMP63-Q1 , TMP64-Q1 Dear BU, My customer used TMP61-Q1 and they want to know how to change the Rbias. Does it settle down by 10Kohm or could customer change to other value.

  • TMP64-Q1: Could I get the Thermistor Tool sheet password to change the top resistor value away from 47 kΩ?

    Resolved
    Part Number: TMP64-Q1 Other Parts Discussed in Thread: TMP63 Hi, In the datasheet it is recommended to leave the top resistor at 47 kΩ, but it may make sense in some applications to do that anyway. Could you provide the PW to change the value in…

  • RE: TMP61-Q1: Any way to increase the slope

    Hi Jalen, If customer change from TMP61 to TMP63 or TMP64, ideally the resistance changes versus temperature world be larger right? Would it be another solution to help RnD improve the low temp worse differentiate issue? Thanks. Alex

  • RE: National Semiconducor NTC thermistor reference

    Resolved
    Dear Vincent - We cannot confirm this part number for you and TI does not make this device or any NTC - sorry about that. We do make temperature sensing PTCs which are silicon based, but not one in this effective resistance at 25C range. (we make 10k…

  • RE: TMP236-Q1: Operation range?

    Resolved
    Igor, In this case, the TMP236 is the only part in the analog portfolio with that high of a gain and with positive slope, and covering the measurement range you need. Two suggestions to consider - 1. You could use diode(s) on the negative terminal…

  • [FAQ] How to design for over temperature protection with a thermistor and a comparator

    Resolved
    Other Parts Discussed in Thread: TMP63-Q1 Is there a solution for over temperature protection using a comparator with external hysteresis? My automotive design requires the comparator output to toggle high when a temperature of 100C is reached. I would…
