APPLICATIONS
P9222-R/RN Datasheet The P9222-R/RN is an integrated single-chip wireless power receiver IC (Rx) for up to 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 (Tx) for optimized power delivery. The P9222-R/RN is highly efficient at light loads and very wellsuited for low-power applications such as earbuds case charging. A unique Ping detect feature gives the user an early indication of the wireless charger connection and improves thermal performance at the end of complete battery charging.
