Overview
Description
The P9221-R is a highly-integrated, Qi-compliant wireless power receiver targeted for 15W applications. Using magnetic inductive charging technology, the receiver converts an AC power signal from a resonant tank into a regulated 9V or 12V DC output voltage. The integrated, low-RDS(ON) synchronous rectifier and ultra-low-dropout regulator offer high-efficiency, making the product ideal for battery-operated applications.
The receiver includes a 32-bit ARM Cortex®-M0 processor offering a high level of programmability. The device outputs proprietary alignment guide information for optimum coupling between the receiver and the transmitter, and features a programmable current limit. The innovative over-voltage protection scheme eliminates the need for additional capacitors generally required by other receivers, minimizing the external component count and cost. Together with the P9242-R transmitter, the P9221-R is a complete wireless power system solution for 15W applications. The P9221-R is available in a space-saving 2.64 × 3.94 mm 52-WLCSP package. It is rated for the -40°C to 85°C ambient operating temperature range.

P9221-R Wireless charger Way to tell the transmitter max power?
I am using an MCU to control the P9221-R and I need a way to determine the max current that can be consumed out of VOUT. This will change depending on the transmitter connected to the P9221-R. Is there a register or way to determine the max amount ...

P9242-R Not working properly
... with the 3 different phones we have tested it seems to work fine, except for item 1 of course, one of these kits is the P9221-R-EVK. Any idea of why this could be happening? 3) Sometimes the prototype goes into an unknown state where it stays powering everything ...
