Wireless Power Receiver
for 15W Applications
P9221-R
Datasheet
Description
The P9221-R is a high efficiency, Qi-compliant wireless power
receiver targeted for applications up to 15W. Using magnetic
inductive charging technology, the receiver converts an AC power
signal from a resonant tank into a regulated DC output voltage
setting with 9V and 12V. The integrated, low RDS (ON) syn-
chronous rectifier and ultra-low dropout offer high efficiency making
the product ideally suited for battery-operated applications.
The P9221-R includes an industry-leading 32 bit ARM® Cortex®-
M0 processor offering a high level of programmability. In addition,
the device features proprietary alignment guide information for
optimum coupling between the receiver and the transmitter, a
programmable current limit, and a patented over-voltage protection
scheme eliminating the need for additional capacitors generally
used by the receivers, minimizing the external component count
and cost. Together with the P9242-R transmitter (T_X), the P9221-R
is a complete wireless power system solution for power
applications up to 15W.
The P9221-R is available in a 52-WLCSP package and it is rated
for a 0 to 85°C ambient operating temperature range.
