Product Datasheet
Introduction
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. 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 communication protocols with optimal efficiency.
The device includes the control circuit required to modulate
the load to transmit WPC-compliant or PMA-compatible
message packets to the base station. It uses minimal
external components 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.
Typical Application Circuit
Packages: WLCSP-36 6x6 balls (3.06mm x 2.9mm) (See page 33)
TQFN-32 5x5mm (See page 35)
