I am trying to connect my lithium ion battery with packp and packn connections to the bq24251. However, on the bq24251 datasheet there is a layout that suggests using a battery that has a thermistor which then connects to the TS pin. I have tried testing the charger on a breadboard using my battery and leaving the TS pin open and it seems to work correctly. Is it alright to leave the TS pin open? Or is there an alternative method I should use when using a battery without a thermistor.
