P9418 60W Wireless Power Receiver with WattShare™ TRx Mode
●As a wireless power transmitter, the P9418 features an on-chip full/half-bridge inverter, a pulse-width modulation (PWM) generator, a modulator/demodulator for communication, and a microcontroller to produce an AC power signal to drive an external L-C tank. As a receiver, the device receives an AC power signal from a wireless transmitter and converts it to a rectified output voltage, which can power devices or supply the charger input in mobile applications. For optimized power delivery, the P9418 integrates a high-efficiency Synchronous Full Bridge Rectifier and control circuitry that modulates the load to send message packets to the Transmitter (Tx).
●The P9418 features multiple-time programmable (MTP) non-volatile memory to easily update control firmware and device functions.
●Also, the device includes over-temperature and voltage protection. Fault conditions associated with power transfer are managed by an industry-leading 32-bit ARM® Cortex®-M0 processor that offers a high level of programmability while consuming extremely low standby power. The processor also controls GPIOs to indicate operating and fault modes.
●The P9418 is available in an ultra-small 70-WLCSP package.
