Qi certification Single coil 15w wireless charging receiver
1. Wireless charging module:
The 15W-RXP9221-R is a high efficiency, Qi-compliant wireless power receiver targeted for applications up to 15W. Using magnetic inductive charging technology, the receiver converts an AC power signal from a resonant tank into a regulated DC output voltage setting with 9V and 12V. The integrated, low RDS (ON) syn-chronous rectifier and ultra-low dropout offer high efficiency making the product ideally suited for battery-operated applications.
15W-RXP9221 transmitter module consists of the L*W 40*30mm coil (see later description) with an integrated electronics PCB. Already passed WPC1.2.2 QI certification .
The 15W-RXP9221 module offers a Coil-to-coil charging distance up to 4-6mm(+/- 1mm).
The 15W-RXP9221 working with transmitter TX9242 can provides 12V1.25A (Max) output power to device charging .
Thermal management system is designed to stop power transfer when the sense temperature is exceeding safety threshold while auto-resume mechanism would rescan the device when the temperature cool down to safety level
