Hi,

Please visit https://e2e.ti.com/support/power-management/f/196/t/874557 for BQ2589X: Schematic Review and PCB Layout Design Tips and https://e2e.ti.com/support/power-management/f/196/t/875386 for BQ2589x/BQ25898x FAQs. BQ25890H is similar to BQ25890.

The TS pin connection is dependent if a thermistor is in use or not. Please refer to the links above for the details.

Thanks,

Ning
