P9221-R Datasheet | Renesas

Description The P9221-R is a high-efficiency, Qi-pliant 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 ponent count and cost. Together with IDT’s P9242-R transmitter (Tx), the P9221-R is a plete 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.
