Design bq51003
SLUSBC8B – DECEMBER 2013 – REVISED MARCH 2017 bq51003 Highly Integrated Wireless Receiver Qi (WPC v1.2) Compliant Power Supply
1 Features 3 Description The bq51003 is an advanced, integrated, receiver IC
for wireless power transfer in portable applications
optimized for 2.5-W and below applications. The
device provides the AC-DC power conversion while
integrating the digital control required to comply with
the Qi v1.2 communication protocol. Together with
the bq500210 transmitter controller, the bq51003
enables a complete contact-less power transfer
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 through 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 …
