BQ24610: charging current

Zoe Ko
Expert 3810 points
Part Number: BQ24610

Hi team,

Could you help check how to set charging current?

You can see in below figure.

On the datasheet 9.3.2, it should be adjust Rsr.

But on table 4, it looks change the inductor value.

Could you let me know what are the values to 5A?

Thank you!

    Hi Zoe,

       The equation is based off of the value of your sense resistor (RSR) and the voltage source on ISET1 pin. The inductor and output capacitor do not factor in the calculation of charge current, so their value does affect your charge current. Please read the rest of the datasheet for more infomration on how value of inductor and capacitor should be sized, specifically sections 10.2.1.2 and section 9.3.10
