This evaluation module (EVM) is a complete evaluation system for the bq2750x. The EVM includes one bq2750x circuit module, a current sense resistor, one thermistor, and Windows®-based PC software. An EV2300 board for gas gauge interface is required to interface this EVM with the PC and can be purchased separately. The circuit module includes one bq27500 or bq27501 integrated circuit (IC), one TPS71525 IC, 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 interface board and software, the user can read the bq2750x data registers, program the chipset for different pack configurations, log cycling data for further evaluation, and evaluate the overall functionality of the bq2750x solution under different charge and discharge conditions.
