In a design I made, I am using a BQ24610 coded battery charge controller and charging a 3.7V battery. I had no problems with the design and test parts. But I want to know exactly how this system works. For example, I wonder how the mosfets on the ACDRV pin and the mosfets connected to the PH pin work. Apart from these, what function does the PWM control logic section and the System Power Selector Logic section in the IC have? Finally, how does this IC set preconditioning, constant current and constant voltage charging phases? Thank you in advance for your answers.

 

Search for the datasheet and it will tell you.
