The bq27000EVM is a complete evaluation system for the bq27000 single cell Li-Ion and Li-Polymer battery gas gauge IC. The EVM includes one bq27000 circuit module. The circuit module includes one bq27000 IC, a current sense resistor and all other components on-board necessary to calculate remaining battery capacity and predict a system's time to empty.
The circuit module connects directly across the cell in a battery and provides connections for a battery charger and system load. 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. The program includes a data logging utility to record and store bq27000 activity during charge/discharge cycles.
An EV2300 board is required to interface this EVM with the PC and can be purchased separately.
