The P9222-R is an integrated single-chip wireless power receiver IC (Rx) for up to 5W applications. The P9222-R 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 is available in a RoHS ultra-small WLCSP-40 package and it is rated for a -40°C to +85°C ambient operating temperature range.
