1 / 31 page  Datasheet P9412 30W Wireless Transmitter/Receiver (TRx) R35DS0011EU0120 Rev.1.2 Jul.6.21 Page 1 © 2021 Renesas Electronics The P9412 is a 30W highly integrated single-chip wireless power Wattshare ™ transmitter/receiver IC (TRx) with a high-performance capacitive divider. The device can be configured to receive or transmit AC power through magnetic induction. When the device is configured as a wireless power transmitter (Tx), it uses on-chip full/half-bridge inverter, PWM generator, modulator/demodulator (for communication) and micro controller to produce an AC power signal to drive external L-C tank. As a wireless power receiver (Rx), the device receives AC power from a wireless transmitter and converts it to a rectified output voltage, which can be used to power downstream devices or supply the charger input in mobile applications. The P9412 integrates a high-efficiency synchronous full bridge rectifier and control circuitry to modulate the load and send message packets to the Transmitter for optimized power delivery. The device features Multiple-Time Programmable (MTP) non-volatile memory which allows easy firmware updates. The P9412 includes over-current, over-voltage, and over-temperature protections. Fault conditions are managed by an industry-leading 32-bit ARM® Cortex®-M0 processor offering high programmability with low standby power ideal for mobile applications. The processor can also control GPIOs to indicate operating and fault modes. The device is available in a WLCSP-81 package.
