RT1650

Wireless Power Receiver Compliant with WPC

General Description

The RT1650 is a wireless power receiver compliant

 High Accurate Received Power Calculation for

FOD Function

with WPC V1.1 standard. The RT1650 integrates a

synchronous full-bridge rectifier,

low dropout

 10-bit ADC for Voltage/Current Measurement

 Coil Power Loss Modeling for Optimized

Compensation

regulator, and a Micro Controller Unit (MCU) for control

and communication. The device receives AC power

from a WPC compatible wireless transmitter and

provides output power up to 7.5W, which could be used

as a power supply for a charger of mobile or consumer

devices.

 Adaptive Power Offset Compensation

 Low Quiescent Embedded 32-bit ARM Cortex-M0

MCU

 32KB ROM/OTP, 1KB SRAM and 272B MTP

 Easy Tuning for Communication and Control

Parameters

The MCU-based controller can support bi-direction

channel communication including Frequency Shift

Keying (FSK) demodulation for power signal from the

transmitter and Amplitude Shift Keying (ASK)

modulation for power signal to the transmitter. The

RT1650 provides Foreign Object Detection (FOD)

function to meet the requirement after WPC V1.1. It

communicates with the transmitter for the received

power to determine if a foreign object is present within

the magnetic interface. This provides a higher level of

safety.

 Support Bi-direction Channel Communication

 FSK Demodulation for Power Signal from

Wireless Power Transmitter

 ASK Modulation for Power Signal to Wireless

Power Transmitter

 Programmable Temperature Control

 Programmable Charge Status Packet

 Support Alignment with Transmitter

 Support Enable, Charge Complete and Fault

Control Inputs

The RT1650 provides a programmable dynamic

rectifier voltage control function to improve power

efficiency, a programmable power management control

for maximum power delivery, a programmable current

limit for suitable load setting, a programmable temperature

setting with external NTC for thermoregulation, and

proper protection functions such as UVLO, OVP, and

OTP.

 Receiver Controlled EPT Packet

 Over Current Limit

 Over Voltage Protection

 Thermal Shutdown

 CSP 3.0mm x 3.4mm 48B (Pitch = 0.4mm)

 Low Profile (0.5mm Max.)

Applications

 WPC Compliant Receivers

 Cell Phones & Smart Phones

 Digital Cameras

Features

 Single-Chip WPC V1.1 Compliant Receiver

 Integrated Synchronous Rectifier Switch

 Support Output Power up to 7.5W

 High Rectifier Efficiency up to 96%

 High System Efficiency up to 80%

 Programmable Loading for Synchronous Rectifier

Operation

 Power Banks

 Wireless Power Embedded Batteries

 Headsets

 Portable Media Players

 Hand-held Devices

 Programmable Dynamic Rectifier Voltage Control

for Optimized Transient Response and Power

Efficiency
