1 / 44 page  15W Wireless Charging Transmitter with Bi-directional Data Communication P9242-R3/RB Datasheet © 2019 Integrated Device Technology, Inc. 1 May 17, 2019 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 IDT P9242-R3 is a highly-integrated 15W magnetic induction wireless power transmitter with in-band, bi-directional data com- munication requiring no additional circuitry. The communication channel can be used for proprietary device authentication and secure system data transfer. The P9242-R3 includes a 32-bit ARM®* Cortex®-M0 processor, foreign object detection (FOD), wide input voltage range operation, full bridge drivers, and on-chip simultaneous voltage and current demodulation. In addition, the P9242-R3 features programmable over-current protection, programmable LED output blinking pattern, and I2C serial interface protocol to read back information such as voltage, current, and fault conditions. This standard device is compliant to the WPC-1.2 specification. Combined with the P9221-R3 receiver, the P9242-R3 forms a complete wireless power system solution for 15W applications with bi-directional data communication. The P9242-R3 has a bootloader and application firmware pre- programmed into the internal one-time programmable (OTP) memory. The P9242-RB, which is pin-to-pin compatible with the P9242-R3, has only the bootloader pre-programmed into the internal OTP memory and uses external flash for the application firmware so that it can be changed for specific system requirements. The P9242-R3 is available in a space-saving 48-VFQFPN package. It is rated for -40°C to +85ºC ambient operating temperature range. Typical Application Circuit * ARM® and Cortex® are trademarks of ARM, Ltd. Features Supports bi-directional data communication Enables authentication and system data transfer Up to 15W of power transfer 87% end-to-end efficiency when combined with the P9221-R3 VIN range: 4.25V to 21V Integrated drivers for external power FETs Integrated step-down switching regulator Simultaneous voltage and current demodulation Standard device compliant with the WPC-1.2 specification Supports the I2C interface protocol -40°C to +85°C ambient operating temperature range 6 × 6 mm, 48-VFQFPN package, Pb-free Typical Applications Industrial Equipment Consumer Electronics Medical Equipment |
