bq2026 Evaluation Software
The purpose of the bq2026 evaluation board and the bq2026EVM evaluation software is to demonstrate
the functionality of the bq2026. The bq2026 evaluation board supports both the bq2026DBZR (SOT23-3)
and bq2026LPR (TO-92) packages but only one package can be evaluated/programmed at any time.
The bq2026 is a 1.5K-bit serial EPROM containing a factory-programmed, unique 48-bit identification
number, 8-bit family code, and a 64-bit status register.
The bq2026 is ideal for applications such as battery pack configuration parameters, record maintenance,
asset tracking, product revision status, and access-code security.
