bq2050 Overview
Key Specifications
Package: SOIC
Pins: 16
Operating Voltage: 4.25 V
Max Voltage (typical range): 6.5 V
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.
Key Features
- Conservative and repeatable measurement of available capacity in Lithium Ion rechargeable batteries

- 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
- Self-discharge compensation using internal temperature sensor
- 16-pin narrow SOIC
