Wireless connectivity
- Links the dock with the companion robot and supports contactless charging, with protection circuitry.
- A central STM32G4 control unit coordinates the system, communicating with the wireless, signal-conditioning, power-management, and PFC sections.
Signal conditioning
- Monitors current and uses operational-amplifier and comparator circuits to prepare and check signals.
Power management
- Handles DC/DC conversion, regulation, LDOs, voltage and fuse protection, and power monitoring. The dock can also receive power from a wired charger.
PFC controllers and gate drivers
- Manage power-factor correction and switching, supporting efficient power delivery to the charging system.
