Dual Mode Wireless Power Receiver for 5W Applications

The P9225-R is a high-efficiency wireless power receiver (Rx) that uses magnetic inductive charging technology to convert 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 battery operated 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, and 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.
