The bq26500EVM is a complete evaluation system for the bq26500 single cell Li-Ion and Li-Polymer battery gas gauge IC. The EVM includes one bq26500 circuit module, an EV2300 PC interface board for gas gauge IC evaluation, a USB cable, and a CD ROM including windows-based PC software and support documentation. The circuit module includes one bq26500 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 EV2300 is a USB-based interface board for a PC that can be used to evaluate battery fuel gauge circuits designed with Texas Instruments' ICs. The EV2300 has connections on it for a USB cable and also accepts inputs from a battery fuel gauge circuit's communication port (SMBus or HDQ). By running the appropriate PC software for the corresponging fuel gauge IC, the EV2300 interface board allows the user to evaluate the battery fuel gauge circuit.
