Overview
Wireless Power Receiver for Low Power 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.
Low undervoltage 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.
