15w Wireless receiver scheme
1. Wireless charging module:
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 requlated 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@ MO 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 (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 85C ambient operating temperature range.
