P9222-R/RN Wireless Power Receiver for Low Power Applications Datasheet

PublishTime：2023-02-28

●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 well-suited 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. Low under-voltage lockout (UVLO) threshold allows the receiver to start up even with a weaker digital ping strength signal from a transmitter over an extended area.
●The device includes over-temperature and under/over-voltage protection. The internal over-voltage clamping protects the rectifier output from rising above the overvoltage level when the receiver is quickly moved from a low-coupling position to a high-coupling position. The integrated 32-bit ARM® Cortex®-M0 processor (trademark of ARM, Ltd.) offers a high level of programmability and design parameters that can be easily configured through the I²C interface or an external EEPROM.
●The P9222-R default firmware factory programmed in internal OTP is WPC 1.2.4 Qi Baseline Power Profile (BPP) compatible. The P9222-RN default factory firmware programmed in internal OTP is latest WPC 1.3 Qi Baseline Power Profile (BPP) compatible.
●The P9222-R/RN is available in a RoHS ultra-small WLCSP-40 package and it is rated for a 0 to 85°C ambient operating temperature range.
