Hello. I would like to inquire about the VBATTERY setting.

1) What values do VBATSET, V, and IBATP mean here?

2) What are the R1 and R2 set to under the conditions below?

* Vin : 24V

* VBATTERY : 19V

* BATSET Pin is GND

Thank you.

Hello Jaeho,

The max battery voltage is 16.8V, I recommend using a different battery charger if you need a battery voltage of 19V.

Best Regards,

Christian.

Thank you for your answer.

I'd like to ask you

1) When It is Vin 19V / Battery Voltage : 16.8V, What are the R1 and R2?

2) When BATSET Pin is GND, What are the measurement?

3) What's mean the IBATP?

Hello Jaeho,

Is this for a new project? The BQ24703 is a legacy device. TI's newer chargers can provide many benefits, including higher efficiency, higher integration, lower BOM count, and more features. If you send me the design requirements, then I can help suggest a charger which would fit your application best.

Best Regards,

Christian.
