NU1619 Datasheet  
NU1619: High Efficiency, High Integration Wireless Power  
Receiver/Transmitter  
1 Features  
3 Descriptions  
•
Integrated 28V high-efficiency  
synchronous rectifier  
NU1619 is a highly integrated and highly  
efficient wireless power receiver. It integrates  
a synchronous rectifier designed for a wide  
frequency range and a programable low drop-  
out regulator for the optimal system efficiency.  
The regulator can provide a wide range  
regulated voltage or current output; both can  
be programmable through an I2C interface.  
•
Integrated Low-Dropout LDO to Provide  
Regulated Output Programmable Vout  
from 3.5V to 20V with 40mV step  
Programmable Iout regulation from 0.1A to  
2.2A with 20mA step  
Local thermal loop to dynamically  
regulate output power  
Integrated full bridge inverter and PWM  
control

NU1619  
can  
conduct  
bi-directional  
communication with a transmitter system  
through ASK and FSK. The communication is  
compliant with WPC.

•
Programmable FOD gain and offset  
1.8V reference voltage output  
V5V supply path management  
Robust OVP, OCP, OTP, and SCP  
10 Bits ADC for voltage, current and  
temperature measurement  
Integrated 32Bit MCU  
NU1619 can also be operated as a transmitter  
(Tx) to charge another receiver. Only few  
external components are needed and  
maximum 10W power can be transferred.

I2C programmability  
In-system programmability  
Bi-directional communications ASK + FSK  
INT Output  
NU1619’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.  
54-WCSP 2.90mm x 4.04mm, 0.4mm pitch
