产品概述

The DS2786BG+ is a stand-alone OCV based fuel gauge in 10 pin TDFN package. This device estimates available capacity for rechargeable Li-ion (Li+) and Li+ polymer batteries based on the cell voltage in the open-circuit state following a relaxation period. The open-circuit voltage (OCV) is used to determine relative cell capacity based on a lookup table stored in the IC. This capability makes accurate capacity information available immediately after a battery pack is inserted. The DS2786B uses coulomb counting as a secondary means of estimating relative capacity, remaining capacity is reported in percent along with cell voltage, current and temperature information. Cell characteristics and calculations are stored in on-chip EEPROM. Temperature data is available from an on-die sensor, resistance measurements of a pack identification resistor and pack thermistor are supported by ratiometric measurements on two auxiliary inputs.
  • Supply voltage range is 2.5V to 4.5V
  • Operating temperature range from -20°C to 70°C
  • Measurement and estimated capacity data are accessed through an I2C interface
  • Relative capacity calculated from coulomb counter and open-circuit cell voltage (OCV) battery model
  • Accurate warning on low battery conditions, low power consumption
  • Optimized for smart phones with push-mail feature
  • 12bit battery voltage measurement with ±10mV accuracy, 1.22mV LSB(0V to 4.5V) input range
  • 11bit bidirectional current measurement with 25µV LSB ±51.2mV dynamic range, 1.67mA LSB at ±3.4A
  • Current accumulation measurement resolution ±204.8mVh and ±13.65Ah (RSNS = 15mR) range
  • Internal temperature measurement of 0.125°C LSB, ±3°C accuracy
