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. USB-based interface board for evaluation of battery fuel gauge circuits developed with fuel gauge ICs using the HDQ and SMBus communication protocol Provides interface between intelligent battery circuit and a Windows-based PC Connects to the USB port of a PC Allows for on screen display and programming of gas gauge register functions when used with the appropriate PC software Colour:White Material:plastic Package Contents: 1 x EV2300 TI HPA002 Interface Development Tools Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
