P9222-RAZGI8

P9222-RAZGI8 is a wireless power receiver for low power applications. It is an integrated single-chip wireless power receiver IC (Rx) for upto 5W applications implementing in-band, bi-directional data communication with no additional circuitry. The device receives an AC power signal from a wireless power transmitter, such as the P9235A-RB WPC Qi BPP Wireless Transmitter IC, and converts it to a rectified output voltage, which can be used to power devices or supply the battery charger input in a wide range of wireless power applications. The receiver (Rx) integrates a high-efficiency synchronous full bridge rectifier (SFBR) and control circuits that enable bi-directional communication from and to the transmitter for optimized power delivery. Typical application includes wireless power solutions for mobile solutions including wireless earbuds case charging, wearables and fitness trackers, mobile devices, hearing aids case charging.
