Description

The P9221-R3 is a high efficiency 15W magnetic induction wireless power receiver with in-band, bi-directional data communication with no additional circuitry. The communication channel can be used for proprietary device authentication and secure system data transfer. The P9221-R3 integrates a 32-bit ARM Cortex®-M0 processor, low RDS(ON) synchronous rectifier, and ultra-low dropout regulator making it ideal for high-efficiency, space-constrained receiver applications. The device features a programmable output voltage, current limitation, and foreign-object detection (FOD) settings. An I²C serial interface allows reading information such as voltage, current and fault conditions. The device also features a patented over-voltage protection scheme eliminating the need for additional capacitors, which can minimize the external component count and cost. Combined with the P9242-R3 transmitter, the P9221-R3 forms complete wireless power system solution for 15W applications with bi-directional communication.The P9221-R3 is provided in a 52-WLCSP package (2.64 × 3.94 mm, 0.4 mm pitch), and it is rated for a 0 to +85°C ambient operating temperature range.
