Hello team,

Is it possible to change the VHOT to 60℃?

It is typically 45℃ on the datasheet.

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
