DS2786B Product details

Description

The DS2786B 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.

Features

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 1.22mV LSB, 0V to 4.5V Input Range.
11-Bit Bidirectional Current Measurement 25µV LSB, ±51.2mV Dynamic Range 1.67mA LSB, ±3.4A (RSNS = 15mΩ).
Current Accumulation Measurement Resolution ±204.8mVh Range ±.
