Smart Li-Ion Battery Gas Gauge

The SS4002AG is an SBS-compliant gas gauge IC for battery pack or in-system installation. It maintains an accurate record of available charge in rechargeable batteries. The SS4002AG is designed specifically for Li- Ion batteries, and monitors capacity and other critical battery parameters. The SS4002AG uses an A-to- D converter with Automatic offset error correction for voltage, temperature, and cur rent reporting. The cumulated charge into (or discharge from) the battery is continuously calculated. The onboard ADC also monitors individual cell voltages in the battery pack and allows the SS4002AG to generate control signals that may be used in conjunction with a pack supervisor to enhance pack safety. The SS4002AG supports the smart battery data (SBData) commands and charge -control functions. It communicates data using the 2- wire System Management Bus (SMBus). The data available includes the battery’s remaining capacity, temperature, voltage, current, and remaining run -time predictions. The SS4002AG provides drive pins for LEDs to depict remaining battery capacity from full to empty in 20% or 25% increments with a 4 or 5-segment Display The SS4002AG work s with an external EEPROM The EEPROM stores the configuration information for the SS4002AG such as the self-discharge rate, measurement calibration, and design voltage and capacity. The SS4002AG uses the programmable self-discharge rate and other compensat ion factors stored in the EEPROM to accurately adjust remaining capacity for use and standby conditions based on time, rate, and temperature. The SS4002AG also automatically calibrates or learns the true battery capacity in the course of a discharge cycle from near full to near empty levels. The VREF output regulates the operating voltage for the SS4002AG from the battery cell stack using an external MOSFET By Silicon Standard Corporation
