BQ27426: : external thermistor data

Part Number: BQ27426

Tool/software:

Hi, I want to read the temperature from the external thermistor, according to TRM the thermistor value is read when the OpConfig[TEMPS] bits are 01.

I tried to read these bits from the address 0x64, but I am getting garbage value. What is the process to read these bits through I2C without any application?

And the process to change these bits and read the external thermistor value.

  • Hello Runita, 

    Could you send a pdf of your schematic along with the thermistor part number if you are using a custom PCB. I've attached notes on how to calibrate the thermistor as well in the mean time. If you are using different specs compared to the Samitec 103AT-2 than that could also be the source of your issues as well.

    Thank you,
    Alan
