Texas Instruments BQ2028YZGT
- Part Number:
- BQ2028YZGT
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3250557-BQ2028YZGT
- Description:
- IC EEPROM 4KBIT 12DSBGA
- ECAD Model:
-
- Datasheet:
- BQ2028YZGT
Description
The bq2028 is a 4Kb serial non-volatile memory (EEPROM) with an integrated temperature sensor and LDO linear regulator. It provides pack-side memory storage and temperature monitoring for single-cell system-side battery fuel gauge solutions such as the bq27505-E1. The bq2028 communicates with the bq27505-E1 gauge over a single-wire HDQ interface with a minimal overhead protocol that ensures error-free data transfer.
Features
512 Byte (4Kb) EEPROM
Single Wire HDQ Communications Port
Integrated 2.5V LDO Linear Regulator
Ultra-low power "shutdown" mode (1µA Typical) via auto-timeout and/or host command
Wake up from shutdown via HDQ break
Internal Die-Temperature Sensor
-15°C Range = -40°C to 85°C
Raw AD to Temperature Conversion Performed by Host Firmware
Applications
Battery Pack NVM storage for bq27505-E1 Fuel Gauge:
Manufacturing Data
Operational History
Resistance Tables
