Product Summary

The DS2782E+ is a stand-alone fuel gauge IC. It measures voltage, temperature and current, and estimates available capacity for rechargeable lithium ion and lithium-ion polymer batteries. Cell characteristics and application parameters used in the calculations are stored in onchip EEPROM. Its applications include Digital Still Cameras, Sub-Notebook Computers, Handheld PC Data Terminals, 3G Multimedia Wireless Handsets.

Parametrics

DS2782E+ absolute maximum ratings: (1)voltage range on any pin relative to VSS: -0.3 to 6V; (2)voltage range on VIN relative to VSS: -0.3 to VDD+0.3V; (3)Operating temperature range: -40 to 85℃; (4)storage temperature range: -55 to 125℃.

Features

DS2782E+ features: (1)Precision Voltage, Temperature, and Current Measurement System; (2)Accurate Stable Internal Time Base; (3)Absolute and Relative Capacity Estimated from Coulomb Count, Discharge Rate, Temperature and Battery Cell Characteristics; (4)Accurate Warning of Low Battery Conditions; (5)Automatic Backup of Coulomb Count and Age Estimation to Nonvolatile (NV) EEPROM; (6)Gain and Tempco Calibration Allows the Use of Low-Cost Sense Resistors.
