The P9242-R3 is a highly-integrated 15W magnetic induction wireless power transmitter with in-band, bi-directional data communication 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 complete wireless power system solution for 15W applications with bi-directional data communication.
The P9242-R3 has the bootloader and application firmware pre-programmed into internal one-time programmable (OTP) memory.
The P9242-RB, which is pin compatible with the P9242-R3, has only the bootloader pre-programmed into OTP memory
and uses external flash for the application firmware so that it can be changed for specific system requirements.
The P9242-R3 and P9242-RB are available in a lead-free, space-saving 48-VFQFN package. It is rated for -40ºC to +85ºC ambient operating temperature range.
