BQ26500 用于一节和两节锂离子电池应用领域的整个电池电量监测计
BQ26500 描述
The bq26500, the first in the bqJUNIOR™ family of advanced gas gauge device for handheld applications, is a highly accurate standalone single-cell Li-Ion and Li-Pol battery capacity monitoring and reporting device targeted at space limited portable applications. The device monitors a voltage drop across a small current sense resistor connected in series with the battery to determine charge and discharge activity of the battery. Compensations for battery temperature, self-discharge, and rate of discharge are applied to the charge counter to provide available capacity across a wide range of operating conditions. Battery capacity is automatically recalibrated, or learned, in the course of a discharge cycle from full to empty.
