BQ24020DRCR ISET1 resistor selection

Other Parts Discussed in Thread: BQ24020

Hi All,

I am using BQ24020 charger IC for charging 150mAh battery through USB.

I am unsure about setting the resistor value for ISET1 pin. The datasheet says that the ISET1 resistor is used to set taper and termination threshold current.

Here is what the battery datasheet says on battery charging cut off current.


How should the ISET1 resistor value be set?


Note: The AC input is not used in the design. 


Thanks in advance.


Regards,

Naveen
