BQ25172: Want to change VHOT

Part Number: BQ25172

Tool/software:

Hello team,

Is it possible to change the VHOT to 60℃?

It is typically 45℃ on the datasheet.

Best Regards,
Kei Kuwahara

    Hi Kei,

    The TS function was designed to work with a 103AT thermistor.  If you find a different thermistor with resistance at 60C x I(TS_BIAS) below to give 188mV, then it might work.  But then the COLD and COOL values might be off.

    Regards,

    Jeff
