The bq2050 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. Compensations for batt.
➤ Conservative and repeatable measurement of available capacity in Lithium Ion rechargeable batteries ➤ Designed for battery pack integration - 120µA typical operating current - Small size enables imple- mentations in as little as 1 2 square inch of PCB ➤ Integrate within a system or as a stand-alone device - Display capacity via single- wire serial communication port or direct drive of LEDs ➤ Measurements compensated for current and temperature ➤ Self-discharge compensation using internal temperature sensor ➤ 16-pin narrow SOIC General Description The bq2050 Lithium Ion Power Ga.
