Introduction
1 Introduction
The bq27000EVM includes one bq27000 circuit module, an EV2300 PC interface board for gas gauge
evaluation, a USB cable, CD ROM including windows-based PC software and support documentation. The
circuit module includes one bq27000, a current sense resistor and all other components on-board
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 bq27000 data registers, program the on-chip configuration EEPROM, and evaluate the
functions of the bq27000 under different charge and discharge conditions.
