Texas Instruments BQ2028YZGR

The Texas Instruments bq2028 serial 4Kb nonvolatile memory (EEPROM) with integrated temperature sensor and LDO linear regulator provides pack-side memory storage and temperature monitoring for a single-cell system-side battery fuel gauge solution such as the bq27505-E1.

The bq2028 communicates with the bq27505-E1 gauge over a single-wire HDQ interface with a minimal overhead protocol yet ensures error free data transfer.
