Greetings of the Day
Please help me for my questions!
I am using TL331-Q1 comparator for Low battery protection in MPPT Charger with BQ24650.
Q1. : Can I use Pin-6(3.3-V reference voltage output) for the reference voltage input in TL331-Q1?
Q2. : Does TL331-Q1 have reverse polarity protection?
For PCB layout, we recommend to place all the power components on the same side of the board and use ground layer as shielding.
It is important to place the bypass capacitor close to the drain of the highside MOSFET and the source of the lowside mosefet to minimize the high frequency switching loop.
