Wireless Charging Receiver by Renesas

Note : Your request will be directed to Renesas.

The P9412 from Renesas is a Single Chip Wireless Power Receiver IC for 30 W applications. The device can be configured to receive or transmit an AC power signal through magnetic induction. When the device is configured as a wireless power transmitter (6 W using Wattshare), it uses an on-chip full/half-bridge inverter, a PWM generator, and a modulator/demodulator for communication, and a micro-controller to produce an AC power signal to drive external L-C tank and to power a receiver device (Wattshare™). As a receiver, this IC receives an AC power signal from a wireless transmitter, and converts it into a rectified output voltage, then further divides it in half with the integrated capacitive divider.

The IC has an integrated 32-bit ARM Cortex-M0 processor, synchronous full bridge rectifier and control circuitry to modulate the load and send message packets to the Transmitter for optimized power delivery. It has a 24kB Multiple-time programmable (MTP) non-volatile memory and supports proprietary fast charging modes with authentication. This IC can be controlled via GPIO and I2C interfaces.

The P9412 is available in a WLCSP-81-package that measures 4.02 x 4.02 mm and is ideal for smartphones and other mobile applications.
