NU1652: High Efficiency, High Integration Wireless Power Receiver and

Transmitter

1 Features

3 Descriptions

•

Integrated 38V High-efficiency

Synchronous Rectifier.

Integrated LDO to Provide Regulated

Output Programmable VOUT from 3.5V to

30V with 8mV resolution.

NU1652 is a highly integrated and efficient

wireless power receiver and suitable for up to

70W output power application. It integrates a

synchronous rectifier and a programable low

drop-out regulator. The regulator can provide

a wide range regulated voltage. NU1652 can

conduct bi-directional communication with a

transmitter system through ASK and FSK. The

communication is compliant with WPC.

NU1652 can also be operated as a transmitter

(Tx) to charge another receiver. Only a few

external components are needed and

maximum 15W power can be transferred.

NU1652’s flexibility is provided by an on-chip

32Bit MCU which can customize and optimize

the device for various applications and custom

needs. The programmability includes output

power, bidirectional communication scheme,

system protection, status reporting and error

reporting.

•

Low Dropout of LDO.

Integrated Full Bridge Inverter and PWM

Controller for transmitter.

1.8V Reference Voltage Output.

V5V0 Power Supply Path Management:

Internal LDO or External VDD.

Ultra-Low Quiescent Current in SLEEP

mode: < 15uA.

Robust and Quick-responsive OVP, OCP,

OTP, OPP and SCP.

High Accuracy Current Sense, Accuracy is

0.05%.

8 Channel, 15bit ADC.

•

Integrated 16MHz 32Bit MCU Core.

400kHz I²C Interface.

NU1652 also includes standard protection

functions such as input under-voltage lockout,

In-system Programmability.

Build-in Bi-directional Communications:

ASK/FSK Modulation and ASK/FSK

Demodulation.

Integrated Q Factor Measurement.

Programmable FOD Gain and Offset.

INT Output.
