P9028AC Overview
Description
The P9028AC is an integrated single-chip, dual-mode WPC v1.1.2-compliant and PMA v1.0-compatible, wireless power receiver IC with advanced WPC v1.1.2 Foreign Object Detection (FOD). The device operates with an AC power signal from a resonant tank and converts it into a regulated 5V output voltage, which can be used to supply power to a mobile application.
