General Description

rectional serial link to an external

➤ Conservative and repeatable

measurement of available capac-

ity in Lithium Ion rechargeable

batteries

The bq2050 Lithium Ion Power

Gauge™ 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 termi-

nal and ground to determine

charge and discharge activity of

the battery. Compensations for bat-

tery temperature and rate of charge

or discharge are applied to the

charge, discharge, and self-discharge

calculations to provide available ca-

pacity information across a wide

range of operating conditions. Bat-

tery capacity is automatically recali-

brated, or “learned,” in the course of

a discharge cycle from full to empty.

processor (common ground). The

bq2050 outputs battery information

in response to external commands

over the serial link.

➤ Designed for battery pack inte-

The bq2050 may operate directly

from one cell (V_BAT> 3V). With the

REF output and an external transis-

tor, a simple, inexpensive regulator

can be built for systems with more

than one series cell.
