产品描述

The bq51010B is a family of advanced, flexible, secondary-side devices for wireless power transfer in portable applications. The bq51010B devices provide the AC/DC power conversion and regulation while integrating the digital control required to comply with the Qi v1.1 communication protocol. Together with the bq50xxx primary-side controller, the bq51010B enables a complete contact-less power transfer system for a wireless power supply solution. Global feedback is established from the secondary to the primary in order to control the power transfer process utilizing the Qi v1.1 protocol.

The bq51010B devices integrate a low resistance synchronous rectifier, low-dropout regulator, digital control, and accurate voltage and current loops to ensure high efficiency and low power dissipation.

The bq51010B also includes a digital controller that can calculate the amount of power received by the mobile device within the limits set by the WPC v1.1 standard. The controller will then communicate this information to the transmitter in order to allow the transmitter to determine if a foreign object is present within the magnetic interface and introduces a higher level of safety within magnetic field. This Foreign Object Detection (FOD) method is part of the new requirements under the WPC v1.1 specification.
