bq2052 Overview
Key Specifications
Package: SOIC
Pins: 16
Operating Voltage: 4.25 V
Max Voltage (typical range): 6.5 V
Description
The bq2052 Lithium Primary Gas Gauge IC is intended for battery-pack 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 with the cells to determine discharge activity of the battery.
Key Features
- Accurate measurement of available capacity in Lithium primary batteries such as Lithium Sulphur Dioxide and Lithium Manganese Dioxide
- Provides a low-cost battery monitor solution for pack integration
- Complete circuit can fit less than 1 square inch of PCB space
- Low operating current
- Less than 100nA of data retention current
- Single-wire communication interface (HDQ bus) for critical battery parameters
- Communicates remaining capacity with direct drive of LEDs in 3 selectable modes
- Measurements automatically compensated for discharge rate and temperature
- 16-pin narrow SOIC Gas Gauge IC for Lithium Primary Cells
