The bq27x10EVM includes one bq27x10EVM circuit module. The circuit module includes one bq27x10, a current sense resistor, and all other components onboard necessary to calculate remaining battery capacity and predict system run-time to empty. The circuit module connects directly across the cell in a battery. With the PC interface board and software, the user can read the bq27x10 data registers, program the on-chip configuration EEPROM, and evaluate the functions of the bq27x10 under different charge and discharge conditions. An EV2300 board is required to interface this EVM with the PC and can be purchased separately.
