Описание

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 SDQ™ interface requires only a single connection and a ground return. The SDQ pin is also the sole power source for the bq2026. The small surface-mount package options saves printed-circuit-board space, while the low cost makes it ideal for applications such as battery-pack configuration parameters, record maintenance, asset tracking, product-revision status, and access-code security.
