1.1 Introduction

The BMS083 PCB is a complete charger evaluation module for the BQ2569X/9X-Q1 family of battery and super capacitor chargers. The BQ2569X/9X-Q1 family of ICs are I2C-controlled single-cell charger ICs that operate in both forward/charge/sink but also in reverse/OTG/source mode. Some spins ICs also have forward and reverse bypass (pass through) modes.

This user's guide provides detailed testing instructions for the BQ2569X/9X-Q1 evaluation modules (EVM). Also included are descriptions of the necessary equipment, equipment setup, and procedures. The reference documentation contains the printed-circuit board layouts, schematics, and the bill of materials (BOM).

Throughout this user's guide, the abbreviations EVM, BQ2569X/9X-Q1EVM, BMS083, and the term evaluation module are synonymous with the BMS083 evaluation module, unless otherwise noted.
