Accessing knowledge base.
I’ll add a USB‑C charging circuit so your battery can be charged via USB‑C and feed your existing battery rail.
- Add a USB‑C Receptacle with sink CC configuration and an ESD/TVS Diode; define VBUS/GND.
- Add a single‑cell Li‑ion Charger IC with power‑path and charge‑status LEDs.
- Add a Battery Connector and protection if needed; tie charger BAT to Net (Argon - Li+).
- Wire required passives; update BOM/footprints; verify ERC/DRC.

Plan
Goal
- Integrate a USB‑C charging circuit into the Robo Project to allow charging of the robot’s single battery from a 5 V USB‑C source while keeping the existing battery rail (Net: Argon - Li+) intact and operational.
-
Add USB‑C Interface and Protections
- Select and add a USB‑C receptacle with sink CC configuration.
- Integrate ESD/TVS protection components at the USB‑C connector, ensuring proper connection of VBUS and GND.
-
Incorporate a Li‑ion Battery Charger
- Select a single‑cell Li‑ion charger that supports power‑path or load‑sharing functionality and provides charging status indications (LEDs).
- Configure the charger’s charge current according to battery specifications.
- Connect the charger’s VIN to the USB‑C VBUS net.
-
**Integrate with Existing Battery Rail
- Connect the charger’s BAT output to the main battery net (Argon - Li+), ensuring proper battery protection if needed.
- Retain connection with Electrolytic C5 on the main rail as a bypass/filter component.
-
Schematic Updates and BOM Review
- Create required schematic connections from the new USB‑C circuit to the main power network.
- Add necessary passive components and status LEDs to the schematic.
- Update BOM and footprints to reflect newly added components.
- The USB‑C receptacle is correctly integrated with sink CC and ESD/TVS protection.
- The Li‑ion charger is properly connected with its VIN on USB‑C VBUS and its BAT output to the existing battery rail.
- Status LEDs are integrated and indicate charging activity correctly.
- All changes conform to ERC/DRC checks, parts are available, and the circuit functions without disrupting the original power system.
