Wireless Power Transmitter for 15W Solution

General Description

Features

⚫ Wireless Power Transmitter Compliant

The RT3181C is a highly integrated and scalable

solution for wireless power transmitter applications.

The RT3181C is designed to support the major

wireless power standards - WPC (Qi). The RT3181C

can be configured to various types of transmitter

according to WPC specification.

 WPC qi V1.3

⚫ High Integration with Internal H-Bridge Power

Stage and Current Sense Amplifier, Optimized

for LP-A11 Solution

⚫ High Power with External Power Stage,

Optimized for MP-A5/MP-A11 Solution

⚫ No Current Transformer Required

⚫ Low Quiescent Current Plus

The RT3181C supports fully integrated design for WPC

Base Power Profile A11 transmitter which could be

powered from a 5V output of USB or AC adaptor in low

power applications. The RT3181C is able to support

WPC MP-A5/MP-A11 transmitter design with external

power stage for medium power applications.

 Selectable Ping Cycle in Custom Applications

 Low Current Sleep Mode Options including

“Off” State with Wake Up I/O Pin

⚫ Programmable Thermal Protection

⚫ Support Foreign Object Detection

⚫ Support Fan Speed Control

The RT3181C can be paired with a Smart AC adapter

from selected suppliers to provide reduced system cost

and optimal efficiency over the range of power usage.
