The P9382A from Renesas is a Single-Chip 20 Watt Wireless Power Receiver. The device can also function as a wireless power transmitter but with a lower power level of 6 Watts. It can be configured to receive or transmit an AC power signal through magnetic induction. When the device is configured as a wireless power transmitter, it uses an on-chip full/half-bridge inverter, PWM generator, modulator/demodulator for communication and microcontroller to produce an AC power signal to drive external L-C tank. As a receiver, the device receives an AC power signal from a wireless transmitter and converts it into rectified output voltage, which can be used to power devices or supply the charger input in mobile applications.
The P9382A is available in an ultra-small 53-DSBGA package that measures 2.80 x 4.0 x 0.4 mm and is ideal for use in mobile phones, notebooks and tablets, water or dustproof portable devices, smart home and IoT devices, Wireless power Rx, Tx, and TRx solution for mobile applications.
