Frequently Asked Questions
What is the maximum charging distance for IP6808?
The typical charging distance for IP6808 is 3-8mm between transmitter and receiver coils. This accommodates most phone cases and accessories. The actual range depends on coil size, alignment, and any materials between the coils. For best performance, maintain close coupling between coils.
Design for 3-8mm typical gap. Thicker cases may reduce efficiency.
How do I design the transmitter coil for IP6808?
Transmitter coil design follows Qi specifications. Use 6.3μH inductance with ±10% tolerance for A11 coils. The coil typically has 10-15 turns of Litz wire for optimal high-frequency performance. Coil diameter should be 50mm for standard applications. Follow WPC coil design guidelines for certification compliance.
Use standard A11 coil design for Qi compliance. Contact us for coil supplier recommendations.
Does IP6808 support multi-device charging?
The IP6808 is designed for single-device charging. For multi-device charging pads, multiple IP6808 chips can be used with independent coils, or consider multi-coil designs with appropriate control logic. Each coil requires its own transmitter IC for independent power control.
Use one IP6808 per charging position. For multi-device pads, use multiple ICs.
What safety certifications are required for wireless chargers?
Wireless chargers typically require Qi certification from WPC for interoperability. Safety certifications include CE (Europe), FCC (USA), UL (safety), and possibly others depending on target markets. The IP6808's Qi compliance simplifies certification. Additional testing may be required for thermal safety and EMC compliance.
Plan for Qi certification and regional safety certifications. We can provide certification guidance.
How does the IP6808 communicate with the receiver?
The IP6808 uses the Qi communication protocol, which modulates the power carrier frequency to send data from receiver to transmitter. The receiver sends packets containing power control information, identification, and error data. The transmitter demodulates this information and adjusts power accordingly. This bidirectional communication enables safe and efficient power transfer.
Communication is automatic per Qi standard. No additional configuration needed.
Can IP6808 work with any Qi-compatible receiver?
Yes, IP6808 is Qi-compliant and works with any Qi-certified receiver device. This includes smartphones from Apple, Samsung, Google, and other manufacturers that support Qi charging. The IC automatically negotiates power levels based on the receiver's capabilities, ensuring compatibility across the Qi ecosystem.
IP6808 works with all Qi devices. No compatibility concerns for standard Qi receivers.
