Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Overview:

The P9222-RAZGI8 is an integrated single-chip wireless power receiver IC (Rx) for applications up to 5W. The P9222-R is highly efficient at light loads, making it ideal for low-power applications such as earbud box charging. The unique Ping detection feature allows users to indicate the wireless charger connection early and improves thermal performance at the end of the battery charge. The low voltage lock (UVLO) threshold allows the receiver to start even if the transmitter's digital ping strength is weak over the extended area.

The device includes over and under/over voltage protection. Internal overvoltage clamping protects the output of the rectifier from rising high voltage heights when the receiver rapidly moves from a low to a high coupling position. Integrated 32-bit ARM®Cortex®-M0 processor (ARM, Ltd. Provides a high level of programmability and design parameters that can be easily configured via an I2C interface or external EEPROM.

The P9222-R is available in a RoHS subminiature WLCSP-40 package and is rated for ambient operating temperatures ranging from -40°C to +85°C.
