FAE Expert Insights
"The IP6806 is ideal for adding wireless charging to compact devices. The WLCSP package is tiny - perfect for space-constrained designs like TWS earphone cases. The integration level is excellent with rectifier and regulator in one chip. I've used this in several wearable projects with good results. The 5W output is sufficient for small batteries. For larger devices, consider higher-power receiver solutions. The Qi compliance ensures compatibility with standard charging pads."

Frequently Asked Questions
What coil should I use with IP6806?
IP6806 works with standard Qi receiver coils, typically 10-15 turns with 10-15μH inductance. The coil size depends on your device dimensions - common sizes are 30-40mm diameter for smartphones, smaller for wearables. Use Litz wire for best high-frequency performance. The coil should be placed where it can couple effectively with transmitter coils.
Use standard Qi receiver coils. Match coil size to your device dimensions.
Can IP6806 charge a battery directly?
IP6806 outputs regulated 5V, which can charge a battery through an external charger IC. For lithium batteries, use a dedicated battery charger IC between IP6806 and the battery. The 5V output can also power devices directly or supply a PMIC. Direct battery connection without proper charging control is not recommended.
Add a battery charger IC for lithium battery charging. Contact us for charger recommendations.
How do I position the receiver coil in my device?
Position the receiver coil where it can match typical transmitter coils. For smartphones, this is usually centered on the back. Avoid metal objects directly behind the coil - use ferrite shielding if necessary. Maintain specified distance from metal components. The coil should be accessible for magnetic coupling with charging pads.
Center the coil on the device back. Use ferrite shielding if metal is behind the coil.
What is the thermal performance of IP6806?
IP6806 has good thermal performance for its power level. At 5W output, the IC typically operates within safe temperature limits. Thermal performance depends on PCB copper area, ambient temperature, and charging duration. Use thermal vias under the chip and adequate copper area for heat spreading. The IC includes over-temperature protection for safety.
Provide adequate copper area for heat dissipation. The IC has built-in thermal protection.
Does IP6806 support higher power like 10W or 15W?
The IP6806 is designed for 5W Baseline Power Profile. For higher power wireless charging (10W or 15W), consider other receiver solutions that support Extended Power Profile. Higher power requires different coil design, thermal management, and communication protocols. Contact us for high-power receiver recommendations.
IP6806 is for 5W applications. Contact us for 10W or 15W receiver solutions.
How do I test the wireless charging function?
Test wireless charging using a Qi-certified transmitter pad. Place your device on the pad and verify charging starts. Check output voltage with a multimeter. Monitor temperature during extended charging. Test with various transmitters to ensure compatibility. Use a USB power meter to measure actual power transfer. Qi test equipment can verify compliance.
Use Qi-certified charging pads for testing. Verify with multiple transmitter brands.
