NU1007 is a highly integrated 9V/10W  
full-bridge power stage IC optimized for  
wireless power transmitter solutions. It  
works with transmitter controller  
SP3100 to create a high-performance  
wireless power transmitter compliant  
with WPC 1.2.3 BPP or customized for  
any customer-requested solutions. The  
device integrates all critical functions,  
such as high-efficiency power FETs, low-  
EMI FET driver, bootstrap circuit, 2.5V  
LDO and lossless current measurement.  
The proprietary current-measurement  
circuit provides accurate current

reading used by FOD (Foreign Object  
Detection) power measurement and in-  
band communication. It eliminates the  
current-sense resistor and amplifier  
circuit, and thus saves cost and

Wireless Power Transmitter  
Compliant with WPC V1.2.3 Baseline  
Power Profile (BPP)  
General Wireless Power Transmitter  
for Consumer, Industrial and Medical  
Applications  
The IC also includes protection functions  
such as input under-voltage lockout,  
short-circuit protection, and thermal  
shutdown. These provisions further  
enhance the reliability of the total  
system solution.
