Wireless Power Receiver IC  
P9028AC  
Features  
Product Datasheet  
Introduction  
. Single Chip Receiver (Rx) Solution  
. WPC v1.1.2 Compliant  
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.  
. PMA v1, v3 Pre-Release Compatible with Options  
. Advanced WPC v1.1.2 Foreign Object Detection (FOD)  
. Programmable FOD setting via external resistor and  
I2C registers  
. Programmable current limit via external resistor  
. Integrated Full-Bridge Synchronous Rectifier  
. Integrated 5V @ 1A LDO Regulator Output  
. Closed-loop power transfer control between TX and  
RX  
. I2C interface provides VRECT, Iout and switching  
frequency values  
. Open-Drain LED Indicator Output  
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.  
. Over-Temperature/Voltage/Current Protection  
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.  
Applications  
. WPC-Compliant and PMA-Compatible Wireless  
Chargers for Mobile Applications.  
. Cellular Mobile Phones  
The P9028AC is available in a 36 ball 3mm X 3mm WLCSP  
or 32 pin 5mm X 5mm TQFN package.  
. Tablets, DSC, DVC and Handhelds  
Typical Application Circuit  
Packages: WLCSP-36 6x6 balls (3.06mm x 2.9mm) (See page 33)  
TQFN-32 5x5mm (See page 35)
