bq2050H Overview
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. pensations for battery temperature, self discharge, and rate of discharge are...
