1.1 Introduction

The Texas Instruments BQ25170EVM is a Li-Ion, Li-Poly and LiFePO4 chemistry battery charger IC for single cell. Charging voltage can be adjusted using external resistors on VSET. Charging current can be set from 60 mA to 750 mA with external resistor on ISET.

This user’s guide describes the characteristics, operation, and use of the BQ25176JEVM evaluation module(EVM). This EVM is designed to help the user evaluate and test the various operating modes of the BQ25176J. 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, BQ25176JEVM, BMS033-004, and the term evaluation module are synonymous with the BQ25176J evaluation module, unless otherwise noted.
