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

. 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)

Ordering information: (See page 38)
