Part Number: TMP64 Other Parts Discussed in Thread: TMP6 Team,
Can you please help with the below customer question:
We are currently using the TMP64 devices (TMP6431QDECRQ1 to be specific) in our project, and used the Thermistor Design Tool from the…
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…
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…
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…
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…
Dear Steven -
Thanks for posting and welcome to E2E! The TMP61-Q1 abs max low operating temp is -65C. The device is linear, so the part will continue along the same way as shown in all the graphs in the data sheet.
Best if you have a look at the design…
HI Prebin,
Please see my comments on your other post regarding layout. Once layout issue is fixed, please run charge profile again to see if same issue persists.
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.

Giorgio,
TI has numerous resources to help you with this. Just go to www.ti.com and type “Thermistor” in the search box. Below links are just a sample:

Dear Patty,
thanks for posting. The Linux driver for the ADC they are using would be appropriate here as this is an analog output device that would be connected to the peripheral that would performing the analog to digital conversion.
