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.
