1.1 Introduction

The Texas Instruments BQ25173-Q1 is a linear charger IC for 1- to 4-cell super capacitor. Charging voltage can be adjusted using external resistor divider between OUT and FB. Charging current can be set from 10 mA to 800 mA with external resistor on ISET.

This user’s guide describes the characteristics, operation, and use of the BQ25173-Q1EVM evaluation module (EVM). This EVM is designed to help the user evaluate and test the various operating modes of the BQ25173-Q1. 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, BQ25173-Q1EVM, BMS085-002, and the term evaluation module are synonymous with the BMS085 evaluation module, unless otherwise noted.
