资 源 简 介
The bq2050H Lithium Ion Power GaugeTM 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 between the negaTIve battery terminal and ground 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 information 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.
Nominal available capacity may be directly indicated using a five-segment LED display.
