  • BQ25882: NTC thermistor design recommended 10k to 100k

    Resolved
    Part Number: BQ25882 Hi team, my customer is asking about NTC thermistor design when they want to change 10k to 100k. Datasheet recommended 103AT-2 thermistor, but they want to use 100k NTC thermistor. is it possible to use it instead? I think TI profile…

  • BQ25171-Q1: Thermistor importance? Do we have a reference design?

    Part Number: BQ25171-Q1 Hi Team, Is it key that a thermistor be connected between the IC and the battery can (i.e. replace the NTC with a standard 10k resistor)? Wanted to see if the fast-charge functionality might be affected. Do you have any reference…

  • [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…

  • ADS1120: Optimal design to measure four thermistors

    TI Thinks Resolved
    Part Number: ADS1120 I have the following circuit to measure four 10K thermistors. My plan was to measure them using the external reference so the source voltage wouldn't be a factor in the temperature calculation. However I feel like I should be using…

  • BQ24650: Designing for Lead Acid Battery without using a Thermistor

    Resolved
    Part Number: BQ24650 I was designing a charge controller for the lead-acid battery using BQ24650. As the ambient (atmospheric) temperature here is around 25 to 30 Deg Celsius we want to use the IC without using the thermistor as mentioned in slva437a. 1…

  • RE: TMP61: Need the temperature-resistor curve/table for customer evaluation

    Dear Zirui - Thanks for the post - please utilize the TMP6-THERMISTOR-DESIGN tool to retrieve the tables you desire, you can choose any of the TMP6 family of parts from the first tab, when starting - would also highly recommend you don't use those tables…
