Hi everyone,

I’m working on a PCB project and I’d like some advice before going too far.

I’m using an ESP32-S3-WROOM-1 and I want to integrate a 1S LiPo battery that charges via USB-C. The idea is that the same USB-C port would both:

• charge the LiPo battery
• handle USB data communication with the ESP32-S3

So basically one USB-C connector for power (charging) and data at the same time.

I’m trying to figure out the best way to design this safely and correctly (power path management, charging IC, USB routing, etc.).

Does anyone have recommendations for:

• suitable charging / power management ICs for this setup?
• how to properly share the USB-C between charging and data?
• any reference designs or common pitfalls to avoid?

(The picture is what I already did, but I'm not sure if it's work)
