Description

The P9225-R is a high-efficiency wireless power receiver (Rx)

capable of operating in both WPC and PMA protocols. Using

magnetic inductive charging technology, the receiver converts an

AC power signal from a resonant tank into a regulated DC output

voltage ranging from 4.5V to 5.5V. The integrated, low RDSON

synchronous rectifier and ultra-low dropout linear (LDO) regulator

offers high efficiency making the product ideally suited for batteryoperated applications.

The P9225-R includes an industry-leading 32-bit ARM®

Cortex®-M0 microprocessor offering a high level of programmability. The P9225-R also features a programmable current limit

and a patented over-voltage protection function eliminating the

need for additional capacitors generally used by the receivers

minimizing the external component count and cost. Together with

the P9038-R transmitter (TX), the P9225-R is a complete wireless

power system solution for power applications up to 5W.

The P9225-R is available in a 52-WLCSP package, and it is rated

for 0°C to 85°C ambient operating temperature range.
