The P9242-R is a highly integrated, magnetic induction, wirelesspower transmitter supporting up to 15W. The system-on-chipoperates with an input voltage range of 4.25V to 21V.The transmitter includes an industry-leading 32-bit ARM®Cortex®-M0 processor offering a high level of programmabilitywhile consuming extremely low standby power. The P9242-Rfeatures two LED outputs with pre-defined user-programmableblinking patterns, buzzer, and programmable over-currentprotection supporting a wide range of applications. The I2C serialcommunication allows the user to read information such asvoltage, current, frequency, and fault conditions. The P9242-Rincludes an under-voltage lockout and thermal management circuitto safe guard the device under fault conditions. Together withthe P9221-R receiver (RX), the P9242-R is a complete wirelesspower system solution.
