Product Datasheet
Introduction
The P9028AC is an integrated single-chip, dual-mode WPC v1.1.2-pliant and PMA v1.0-patible, 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. It includes a high efficiency Synchronous Full Bridge Rectifier and 5V tracking LDO output stage. The P9028AC dual-mode operation automatically detects the transmitter type and initiates either WPC or PMA AC modulation munication protocols with optimal efficiency.
The device includes the control circuit required to modulate the load to transmit WPC-pliant or PMA-patible message packets to the base station. It uses minimal external ponents to reduce overall solution area.
The P9028AC 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.
The P9028AC is available in a 36 ball 3mm X 3mm WLCSP or 32 pin 5mm X 5mm TQFN package.
