bq27546EVM Single-Cell Impedance Track™ Technology
Evaluation Module
This evaluation module (EVM) is a complete evaluation system for the bq27546. The EVM includes one
bq27546 circuit module, with a current sense resistor, and thermistor. The circuit module includes one
bq27546 integrated circuit (IC), and all other onboard components necessary to monitor and predict
capacity. The circuit module connects directly across the cell in a battery. With the EV2300/EV2400
interface board and software, the user can read the bq27546 data registers, program the chipset for
different pack configurations, log cycling data for further evaluation, and evaluate the overall functionality
of the bq27546 solution under different charge and discharge conditions.
