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. Note: The driver on this page is for 32 bit Windows. See the 64 bit driver e2e post for 64 bit Windows 7 driver information.
