bq2050H Overview
Key Specifications
Package: SOIC
Pins: 16
Operating Voltage: 4.25 V
Max Voltage (typical range): 6.5 V
Description
The bq2050H 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
- Accurate measurement of available capacity in Lithium Ion batteries
- Provides a low-cost battery management solution for pack integration
- Complete circuit can fit in as little as 1 2 square inch of PCB
- Low operating current (120µA typical)
- Less than 100nA of data retention current
- High-speed (5kb) single-wire communication interface (HDQ bus) for critical battery parameters
- Monitors and controls charge FET in Li-Ion pack protection circuit
- Direct drive of remaining capacity LEDs
- Measurements automatically compensated for rate and temperature
- 16-pin narrow SOIC
