1.1 Introduction

The BQ51013C is a wireless power supply and produces a 5V output of up to 1A for a 5W design. The device supports Qi version 2.0 and is a 5W Baseline Power Profile (BPP). The receiver is powered by a Qi compliant transmitter using the planer coil at the base of the EVM. Communication protocols and safety features are incorporated into the BQ51013C making the device simple to use.

The USB-optional input feature is provided by Q1; this automatically switches from wireless power to external power when present. The NTC is simulated by a 10kΩ resistor and has the option to be adjusted by a trim pot. Output current can be adjusted using R16 or fixed value can be selected.

This user’s guide describes the characteristics, operation, and use of the BQ51013C EVM evaluation module (EVM). This EVM is designed to help the user evaluate and test the various operating modes. This user’s guide includes setup instructions for the hardware, a schematic diagram, a bill of materials (BOM), and PCB layout drawings for the evaluation module.

Throughout this user's guide, the abbreviations EVM, BQ51013C EVM, BMS044-002 and the term evaluation module are synonymous with the BQ51013C evaluation module, unless otherwise noted.
