1.1 Introduction

The BQ51013C is a wireless power supply and produces 5V out at 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 EVM. Communication protocols and safety features are incorporated into the BQ51013C-Q1 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 10k 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-Q1 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-Q1 EVM, BMS044-002 and the term evaluation module are synonymous with the BQ51013C-Q1 evaluation module, unless otherwise noted.
