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.
