9 x 3mm DSBG or 4.
5 x 3.
5mm QFN Package APPLICATIONS • WPC Compliant Receivers • Cell Phones, Smart Phones • Headsets • Digital Cameras • Portable Media Players • Hand-held Devices 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 enables a complete contact-less power transfer system for a wireless power supply solution.
By utilizing 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 5W applications.
The device integrates a low-impedance full synchronous rectifier, low-dropo...
