Hey everyone,
I am currently working on designing a one-cell battery charge and protect circuit for a simple project I'm working on but don't have too much expertise in this area. Below is an image of the schematic I designed. Charging the battery will use a USB-C port located on the board, and will be limited to 0.5A using R26. What I am unsure about is if both of these ICs are required or if the charging IC has enough safety protections built into it to be sufficient. My main concern is over-discharge protection. Also, if I were to swap the USB c port for a solar panel and adjust R26 according to the solar panel output, would the rest of the circuit be able to be powered while charging the battery? Any other comments regarding the circuit would be appreciated. Thank you!
