The bq2022A is a 1 K-bit serial EPROM containing a factory-programmed, unique 48-bit identification number, 8-bit CRC generation, and an 8-bit family code. A 64-bit status register controls write protection and page redirection. The purpose of the evaluation software is to demonstrate the functionality of the bq2022A. The bq2022A evaluation board can be used for one or two ICs. The bq2022A is ideal for applications such as battery pack configuration parameters, record maintenance, asset tracking, product revision status, and access-code security.
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.
