The bq2052EVM-001 is a complete evaluation system for the bq2052 Primary Lithium Gas Gauge IC. The EVM includes a DM2052 circuit module, an EV2200 PC Interface Board for Gas Gauge Evaluation, a PC serial cable, and Windows-based PC software. The DM2052 circuit module includes one bq2052 IC, a sense resistor, 5 LEDs to display remaining capacity, and all other components onboard necessary to monitor capacity and other critical parameters in a primary lithium-based system. The DM2052 connects directly across the cells in a battery. With the EV2200 interface board and software, the user can read the bq2052 data registers and evaluate the functions of the bq2052 under different discharge conditions.
