The IDT P9020 is a highly-integrated single-chip WPC-compliant wireless power receiver IC optimized for inductive power transfer. The device receives an AC power signal from a compatible wireless transmitter and converts it into a regulated 5V output voltage which can be used to power devices or supply the charger input in mobile applications (wireless battery charging). The P9020 integrates a high-efficiency synchronous full-bridge rectifier, high-efficiency synchronous buck converter, and control circuits used to modulate the load to transmit Qi-compliant message packets to the transmitter station to optimize power delivery. Power delivery is limited to 5W in accordance with the Qi specification.
The device includes over-temperature/voltage protection and a Foreign Object Detection (FOD) method to protect the base station and mobile device from over-heating in the presence of a metallic foreign object. Fault conditions associated with power transfer are managed by the embedded MCU, which also controls status LEDs to indicate operating and fault modes. IDT’s inductive power transfer / wireless battery charging solution is complemented by P9030 transmitter IC.
