FEATURES  
•
Integrated Wireless Power Receiver Solution  
with a 5V Regulated Supply  
DESCRIPTION  
The bq5101x is an advanced, integrated, receiver IC  
for wireless power transfer in portable applications.  
The device provides the AC/DC power conversion  
while integrating the digital control required to comply  
with the Qi v1.0 communication protocol. Together  
with the bq500210 transmitter controller, the bq5101x

93% Overall Peak AC-DC Efficiency  
Full Synchronous Rectifier  
WPC v1.0 Compliant Communication  
Control  
enables  
a complete contact-less power transfer  
–
–
Output Voltage Conditioning  
system for a wireless power supply solution. By using  
near-field inductive power transfer, the receiver coil  
embedded in the portable device receives the power  
transmitted by the transmitter coil via mutually  
coupled inductors. The AC signal from the receiver  
coil is then rectified and regulated to be used as a  
power supply for down-system electronics. Global  
feedback is established from the secondary to the  
transmitter in order to stabilize the power transfer  
process via back-scatter modulation. This feedback is  
established by using the Qi v1.0 communication  
protocol supporting up to 5 W applications.

•
•
Supports 20-V Maximum Input  
Low-power Dissipative Rectifier Overvoltage  
Clamp (VOVP = 15V)  
The device integrates  
a
low-impedance full  
synchronous rectifier, low-dropout regulator, digital  
control, and accurate voltage and current loops. The  
entire power stage (rectifier and LDO) use low  
resistive NMOS FET’s to ensures high efficiency and  
low power dissipation.
