EV2300

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 corresponding fuel gauge IC, the EV2300 interface board allows the user to evaluate the battery fuel gauge circuit. The EV2300 controller is a bq8012 running at 4MHz. The controller firmware is stored in flash memory and is executed by the core at power up after the boot ROM code verifies the integrity words. The controller communicates with target devices through either: a 2-wire SMBus communication port, a 1-wire HDQ port, or a 2-wire E2PROM I2C port. The 2-wire SMBus communication port supports both SMBus and I2C protocols.
