bq27750EVM 1-Series Li-Ion Battery Pack Manager
This evaluation module (EVM) is a complete evaluation system for the bq27750 battery management
system. The EVM includes one bq27750 circuit module and a link to the Microsoft
software. The circuit module includes one bq27750 integrated circuit (IC) and all other onboard
components necessary to monitor and predict capacity, monitor critical parameters, protect the battery
from overcharge, over-discharge, short-circuit, and overcurrent in 1-series cell Li-Ion or Li-Polymer battery
packs. The circuit module connects directly across the battery. With the EV2300 or EV2400 interface
board and software, the user can read the bq27750 data registers, program the chipset for different pack
configurations, log cycling data for further evaluation, and evaluate the overall functionality of the solution
under different charge and discharge conditions using I
