bq27410EVM: Single-Cell Impedance Track™ Technology
This evaluation module (EVM) is a complete evaluation system for the bq27410. The EVM includes one
bq27410 circuit module. The circuit module includes one bq27410 integrated circuit and all other onboard
components necessary to monitor and predict capacity for a system-side fuel gauge solution. The circuit
module connects directly across the battery pack. With the EV2300 or EV2400 interface board and
software, the user can read the bq27410 data registers, program the chipset for different pack
configurations, log cycling data for further evaluation, and evaluate the overall functionality of the bq27410
solution under different charge and discharge conditions. The latest Windows™– based PC software can
be downloaded from the product folder on the Texas Instruments Web site.
