Benefits
- Foreign object detection (FOD)
FOD improves detection accuracy during charging. This enhances operational safety, prevents overheating, reduces damage risk to both the charger and device, and helps extend device lifespan while protecting the user. - High efficiency
Excellent efficiency performance with integrated power management capabilities optimizes energy usage, reduces heat generation, and extends overall system reliability. - Protection features
Embedded protection features include on-chip thermal management, overvoltage, and overcurrent protection to effectively prevent overheating and ensure user and system safety.
- Reduced BOM
Simplifies the implementation of wireless charging systems by minimizing the number of discrete components required, which lowers manufacturing costs, improves reliability, and accelerates time-to-market. - Communication interfaces
Built-in communication interfaces, including I²C, UART and GPIO, enable easy and flexible configuration of parameters, facilitating seamless integration and efficient system control.
