General Description

The bq2050 Lithium Ion Power Gauge™ IC is intended for batterypack or in-system installation to maintain an accurate record of available battery capacity.

The IC monitors a voltage drop across a sense resistor connected in series between the negative battery terminal and ground to determine charge and discharge activity of the battery.

Compensations for battery temperature and rate of charge or discharge are applied to the charge, discharge, and self-discharge calculations to provide available capacity information across a wide range of operating conditions.

Overview

bq2050 Lithium Ion Power Gauge™ IC.

Key Features

Conservative and repeatable measurement of available capacity in Lithium Ion rechargeable batteries.
Designed for battery pack integration - 120µA typical operating current - Small size enables imple- mentations in as little as 1 2 square inch of PCB.
Integrate within a system or as a stand-alone device - Display capacity via single- wire serial communication port or direct drive of LEDs.
Measurements compensated for current and temperature.
