Page 2: Introduction
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 60mA to 600mA with external resistor on ISET. -
Page 3: Test Summary
This section describes the jumpers and connectors on the EVM as well as how to properly connect, setup, and use the BQ25170EVM. Note that the default jumper setting of headers and switches are marked with two dots to indicate the shorting jumper position. This will put the unit into a single cell Li-Ion configuration, 4.2V at 400mA. -
