Overview
Description
The P9222-R-EVK wireless power evaluation board demonstrates the features and performance of the P9222-R 5W wireless power receiver in low-power applications such as earbuds and hearing aids charging cases. The P9222-R-EVK can supply up to 5W power. IDT’s P9235A-RB-EVK Evaluation Board or any other Qi-certified transmitter can be used as the power transmitter for P9222-R-EVK evaluation board testing.
The P9222-R-EVK is a high-efficiency, turnkey reference design supported by comprehensive online resources to significantly expedite design-in effort and enable rapid prototyping. A small 30 × 30 mm power receiver coil is used in the design to meet small form factor device requirements.
Using the P9222-R Windows GUI and the P9222-R-EVK customers can quickly customize operating parameters for their application requirements. Operating parameters such as foreign object detection (FOD) thresholds can be configured by either writing to internal SRAM registers via the I2C interface or by loading the user configuration generated by the P9222-R Windows GUI into an external EEPROM. The P9222-R-EVK has an on-board external EEPROM and connectors to plugin USB to I2C dongle.
