Product Summary

The BQ2083DBT is a SBS-compliant gas gauge IC for battery pack or in-system installation maintains an accurate record of available charge in Li-ion or Li-polymer batteries. The BQ2083DBT monitors capacity and other critical parameters of the battery pack and reports the information to the system host controller over a serial communication bus. It is designed to work with the bq29311 analog front-end (AFE) protection IC to maximize functionality and safety and minimize component count and cost in smart battery circuits. Using information from the BQ2083DBT, the host controller can manage remaining battery power to extend the system run time as much as possible. The applications of the BQ2083DBT are (1)Notebook PCs; (2)Medical and Test Equipment; (3)Portable Instrumentation.

Parametrics

BQ2083DBT absolute maximum ratings: (1)Supply voltage range, VDD relative to VSS: -0.3 V to 6 V; (2)Open-drain I/O pins, V(IOD) relative to VSS: -0.3 V to 6 V; (3)Input voltage range to all other pins, VI relative to VSS: -0.3 V to VDD + 0.3 V; (4)ESDS Rating CDM 1.5 kV ESDS Rating: 50 V; (5)Operating free-air temperature range, TA: -20 to 85℃; (6)Storage temperature range, Tstg: -65 to 150℃.

Features

BQ2083DBT features: (1)Provides Accurate Measurement of Available Charge in Li-Ion and Li-Polymer Batteries; (2)Supports the Smart Battery Specification (SBS) V1.1; (3)Works With the TI bq29311 Analog Front End (AFE) Protection IC to Provide Complete Pack Electronics for 10.8-V or 14.4-V Battery Packs With Few External Components; (4)Based on a Powerful Low-Power RISC CPU Core With High-Performance Peripherals; (5)Integrated Flash Memory Eliminates the Need for External Configuration EEPROM; (6)Measures Charge Flow Using a High Resolution 16-Bit Integrating Converter; (7)Uses 16-Bit Delta Sigma Converter for Accurate Voltage and Temperature Measurements; (8)Programmable Cell Modeling for Maximum Battery Fuel Gauge Accuracy.
