The P9025AC is an integrated single-chip, WPC-1.1.2 compliant wireless power receiver with an advanced Foreign Object Detection (FOD) feature. This device operates with an AC power signal from a resonant tank and converts it into a regulated 5.3V output voltage. The receiver includes a high efficiency Synchronous Full Bridge Rectifier and 5.3V tracking LDO output stage. The P9025AC operation automatically detects the transmitter type and initiates WPC AC modulation communication protocols with optimal efficiency.

The device includes the control circuit required to modulate the load to transmit WPC-compliant message packets to the base station. It uses minimal external components to reduce overall solution area and costs.

The P9025AC employs advanced programmable WPC FOD techniques to detect foreign metallic objects placed on the transmitter base station derived from a transmitted and received power transfer algorithm.
