CV8055D
50W Wireless Power Receiver With 10W Transmitter
The CV8055D is a highly-integrated Wireless power single-chip (SoC) with 50W receiver/10W transmitter dual modes, The device can be configured to receiver or transmitter modes, when the devices work in transmitter mode, The rectifier bridge works as a full/half bridge inverts, has a 16bits PWM generator, with dead-zone regulating. Embedded dual channels demodulation 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/transfer and communication, through a I2C port connect with Mobile phones AP, Embedded 24K Bytes MTP memory to support on line debugging and OTA function, low power design to meet the ENERGY star Requirements. The device includes over-temperature, over-current and over/under voltage protections. The CV8055D is available in 53-WLCSP package with a thickness of only 0.3mm.
