SLUSB22B –OCTOBER 2012–REVISED NOVEMBER 2012

4Kb EEPROM with Single-Wire HDQ Interface and Temperature Sensor

Check for Samples: bq2028

FEATURES

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.

•

Serial Non-Volatile Memory (NVM)

–

512 Byte (4Kb) EEPROM

Provides Battery Pack NVM storage for

bq27505-E1 Fuel Gauge:

Manufacturing Data

Operational History

Resistance Tables

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.
