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…
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…
The first important component selection is the thermistor. For this example, we will use the TMP63-Q1 PTC thermistor.

Malcolm - I have no idea who put that in there, GC is probably GUI Composer - the original example is found here: https://www.ti.com/tool/TMP6-THERMISTOR-DESIGN , in 4th order polynomial TMP vs VDC tab
Be advised to also look at and use the low pass…
Hi Malcolm,
The thermistor design tool contains all of the methods and C code examples for converting ADC measurements to temperature. The LP-MSPM0L1306 uses the voltage divider topology and TI recommends using the 4th order polynomial method for measuring…
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…
Part Number: TMP61 Hi Team,
According to our customer, he has the resistance values table from the product page of TMP61. He wants to know the formula for calculating the resistance values for different temperatures. I have checked the datasheet and…
Part Number: BQ24650 Hai,
I have designed BQ24650 for my lead acid battery and now its in the testing stage. there are a few problems that i face now.
1) the Mppt voltage remains at 0.4V. But once i removed Q2 its working fine. so now there is no…
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.
please see:…
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…
