5W, Qi Wireless Power Receiver with Integrated P9025AC

Rectifier and LDO Output

DATASHEET

Features

Introduction

• Integrated Single Chip Receiver (Rx) Solution

• Integrated Full-Bridge Synchronous Rectifier

• Integrated 5.3V, 1A LDO Regulator Output

• WPC-1.1.2 compliant

The P9025AC is an integrated single-chip, WPC-1.1.2

compliant wireless power receiver with an advanced Foreign

Object Detection (FOD) feature. This device operates with an

AC power signal from a resonant tank and converts it into a

regulated 5.3V output voltage. The receiver includes a high

efficiency Synchronous Full Bridge Rectifier and 5.3V tracking

LDO output stage. The P9025AC automatically detects the

transmitter’s presence and initiates WPC AC modulation

communication protocols with optimal efficiency.

• Advanced WPC v1.1.2 Foreign Object Detection (FOD)

• Programmable FOD setting via external resistor

• Closed-loop power transfer control between Tx and Rx

• Support I C interface with access to:

• Rectifier voltage

• Output current

• Resonance frequency

The device includes the control circuit required to modulate

the load to transmit WPC-compliant message packets to the

base station. It uses minimal external components to reduce

overall solution area and costs.

• Open-Drain LED Indicator Output

• Over-Temperature/Voltage/Current Protection

• 0° to +85°C temperature range

• 5 x 5 mm 32-VFQFPN package

The P9025AC 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

• PC peripherals

• Rugged electronic gear

• Small appliances

• Battery-powered electronics
