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 to a programmable regulated 9V or 12V DC

output voltage. The integrated, low RDSON synchronous rectifier

and ultra-low dropout linear (LDO) regulator offer high efficiency,

making the product ideally suited for battery-operated applications.

The P9221-R includes an industry-leading 32 bit ARM® Cortex®-

M0 microprocessor offering a high level of programmability. In

addition, the P9221-R features a programmable current limit and a

patented over-voltage protection scheme eliminating the need for

additional capacitors generally used by receivers and minimizing

the external component count and cost. Together with IDT’s

P9242-R transmitter (Tx), 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.
