bq27531EVM With bq27531 Battery Management Unit
Impedance Track™ Fuel Gauge and bq24192 4.5-A,
Switch-Mode Battery Charger for Single-Cell Applications
This evaluation module (EVM) is a complete evaluation system for the Battery Management Unit (BMU)
chipset consisting of the bq27531-G1 fuel gauge and bq24192 battery charger. The EVM includes one
bq27531 circuit, including a current sense resistor and one thermistor. In addition, the fuel gauge controls
the bq24192 battery charger's settings and monitors its status via I
chipset provides all necessary components to monitor and predict capacity for a system-side fuel gauge
solution as well as to charge the battery from either an adapter or USB input with up to 4.5-A of charge
current. The circuit module connects directly across the battery pack. With the EV2300 interface board
and software, the user can read the bq27531-G1 data registers, program the chipset for different pack
configurations, log cycling data for further evaluation, and evaluate the overall functionality of the battery
management unit solution under different charge and discharge conditions. The latest Microsoft
Windows
based PC software can be downloaded from the product folder on the Texas Instruments Web
®
site.
