1 Introduction
This EVM interface board enables an IBM-compatible or other type (with required driver for the particular
platform) PC to communicate with Texas Instruments SMBus, HDQ, or DQ interface gas gauges via a
Universal Serial Bus (USB) port. In addition to this board, PC software is required to interpret the gas
gauge data to complete the evaluation system.
1.1 Features
• Fully powered from the USB port
• Capable of providing a 25-mA 3.3-V source
• Complete interface between USB and SMBus, I²C, and HDQ (8/16) interfaces using a simple API
1.2 Kit Contents
• EV2300 circuit module
• Standard USB cable
