1 / 46 page  15W Wireless Charging Receiver with Bi-directional Data Communication P9221-R3 Datasheet © 2017 Integrated Device Technology, Inc. 1 October 20, 2017 P9242-R3 External MCU Tx Side P9221-R3 SCL SDA INT SCL SDA INT External MCU Rx Side FSK ASK SCL SDA INT SCL SDA INT 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 regula- tor 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 a complete wireless power system solution for 15W applica- tions with bi-directional communication. The P9221-R3 is provided in a 52-WLCSP package (2.64 3.94 mm, 0.4mm pitch), and it is rated for a 0 to 85°C ambient operating tem- perature range. Typical Applications Industrial equipment Consumer electronics Medical equipment * ARM® and Cortex® are trademarks of ARM, LTD. Features Supports bi-directional data communication Enables authentication and system data transfer Single-chip solution supporting applications with up to 15W Patented over-voltage protection clamp eliminating external capacitors 87% peak DC-to-DC efficiency when combined with the IDT P9242-R3 Programmable output voltage and current limit Embedded 32-bit ARM® Cortex®-M0 processor Dedicated remote temperature sensing Standard device compliant with WPC-1.2 specification Supports I2C interface 0 to +85°C ambient operating temperature range WLCSP 2.64 3.94 mm, 52-WLCSP package Typical Application Circuit |
