Hi, I am designing a product that uses a single Li-Ion cell pack. The pack has already three connections (Cell -, T and Cell +). The Thermistor second terminal is connected to Cell-. The pack is sealed and is a replacement for the Samsung IA-BP125A Battery.
I want to use the bq27742-g1 gas gauge to measure and monitor the battery pack functioning.
I already connected the bq27742-g1 EVM to the battery and start testing. But have two questions:
1- How can I connect the battery thermistor to the bq27742-g1?
2- Is there any problem of using the bq27742-g1 connected to a battery pack that may have other protection circuit inside?
Thanks for your help and support.
