I want to use two BQ7721603 to configure the protection function for 24 series cells.

How should I configure it when using two ICs?

Thank you.

Hi Kentaro,

The BQ77216 can use the same stacking technique as the BQ7718 stacking shown below – the upper OUT connecting to the bottom OUT through a BJT and a diode. I will attach an image demonstrating this and a link the the BQ7718 stacking guide.
