The P9242-R3 from Integrated Device Technology is a WPC-1.2 complaint, 15W magnetic induction wireless power transmitter 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. It integrates 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. The device has 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. The P9242-R3 is available in a 6 x 6mm, 48-VFQFN package and is rated for -40ºC to +85ºC ambient operating temperature range.
