DS2786

Standalone OCV-Based Fuel Gauge

FEATURES

GENERAL DESCRIPTION

Relative Capacity Calculated from

Combination Coulomb Counter and Open-

Circuit Cell Voltage (OCV) Battery Model

Accurate Warning of Low Battery Conditions

Even On First Cycle (No Learn Cycle Needed)

12-Bit Battery Voltage Measurement:

±10mV Accuracy

The DS2786 estimates available capacity for

rechargeable Li-Ion and Li-Ion 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.

During periods of moderate to high rate discharging,

which preclude OCV measurements, the DS2786

uses coulomb counting as a secondary means of

estimating relative capacity.

1.22mV LSB, 0V to 5V Input Range

11-Bit Bidirectional Current Measurement:

25μV LSB, ±51.2mV Dynamic Range

1.67mA LSB, ±3.4A (R_SNS= 15mΩ)

Current Accumulation Measurement

Resolution:

±204.8mVh Range

±13.65Ah (R_SNS= 15mΩ)

Internal Temperature Measurement:

0.125°C LSB, ±3°C Accuracy

Two 11-Bit Aux Input Voltage Measurements:

±8 LSB Accuracy, Ratiometric Inputs

Eliminate Supply Accuracy Issues

V_OUTPin Drives Resistive Dividers, Reduces

Current Consumption

2-Wire Interface

Remaining capacity is reported in percent, along with

cell voltage, current and temperature information.

Cell characteristics and application parameters used

in the calculations are stored in on-chip EEPROM.

The DS2786 is intended for use on the host side of

portable devices, though it can also be mounted

within a battery pack. Measurement and estimated

capacity data are accessed through an I²C interface.

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.

Low Power Consumption:

Active Current: 50μA typ, 80μA max

Sleep Current: 1μA typ, 3μA max
