Hi,

Good Day.

Customer is following this reference design.

https://www.ti.com/tool/TIDA-050047

If his battery doesn't have TS function then what he should do to TS pin?

Also, what are the function of ILIM_HIZ voltage divider?

Please advise. Thank you very much.

Best Regards,

Hello Ray,

Please permanently bias the TS pin between T2 and T3 as mentioned in Section 9.3.9.5.1 "JEITA Guideline Compliance in Charge Mode" for full charge voltage and charge current regardless of the battery temperature.

The ILIM_HIZ pin is the Input Current Limit Setting and HIZ Mode Control Pin. The input current limit is the lower of this setting and the IINPDM register. The equation for the current limit is in the pin description. The ILIM_HIZ pin can be disabled, at which the IINPDM will decide the input current limit.

Regards,

Mike Emanuel
