The CV8065D  is a highly-intergrated Wireless power single-chip (SoC) with 42W(24V@1.75A)  receiver/transmitter dual modes, The device can be configuraed to receiver or transmitter modes, when the devices work in transmitter mode, The rectify bridge work as full/half Bridge inverter, has a 16bits PWM generator, with dead-zone regulating. Embedded dual channels demodulator for Communication. When device work as receiver mode,

The device receivers an AC power from a wireless transmitter, embedded a high efficiency synchronous full bridge rectifier converts to DC power, Embedded modulation and FSK demodulation circuits supports bi-direction communication,

A Microprocessor manages power receiver/transfor and comunication, through a I2C port connect with

Mobile phones AP, Embedded 16K Bytes MTP memory to support on line debugging and OTA function, low power design to meet the ENERGY star

Reqirements.

The device includes over-temperature, over-current and over/under voltage protections. The CV8065D  is available in 53-WLCSP package.
