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 earbud 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. A 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 undervoltage/overvoltage protection. The internal overvoltage 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 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.
