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