Description

The P9221-R3 is a high efficiency 15W magnetic induction wireless

power receiver with in-band, bi-directional data communication with

no additional circuitry. The communication channel can be used for

proprietary device authentication and secure system data transfer.

The P9221-R3 integrates a 32-bit ARM® Cortex® -M0 processor*,

low-RDS(ON) synchronous rectifier, and ultra-low dropout regula-

tor making it ideal for high-efficiency, space-constrained receiver

applications. The device features a programmable output voltage,

current limitation, and foreign-object detection (FOD) settings. An

I2C serial interface allows reading information such as voltage,

current, and fault conditions. The device also features a patented

over-voltage protection scheme eliminating the need for additional

capacitors, which can minimize the external component count and

cost. Combined with the P9242-R3 transmitter, the P9221-R3

forms a complete wireless power system solution for 15W applica-

tions with bi-directional communication.

The P9221-R3 is provided in a 52-WLCSP package (2.64

 3.94 mm,

0.4mm pitch), and it is rated for a 0 to 85°C ambient operating tem-

perature range.
