General Description
The bq2052 Lithium Primary Gas
Gauge IC is intended for bat-
tery-pack or in-system installation
to maintain an accurate record of
available battery capacity.
monitors a voltage drop across a
sense resistor connected in series
with the cells to determine dis-
charge activity of the battery.
bq2052 applies compensations for
battery temperature and discharge
rate to the available charge counter
to provide available capacity infor-
mation across a wide range of oper-
ating conditions.
The IC
The
Compensated available capacity
may be directly indicated using an
LED display.
The LED display is
programmable and can be config-
ured as two, four, or five segments.
These segments are used to depict
available battery capacity.
bq2052 supports a single-wire serial

the micro-controller to read and
write the internal registers of the
bq2052.
The internal registers in-
clude available battery capacity,
voltage, temperature, current, and
battery status. The controller may
also overwrite some of the bq2052
gas gauge data registers.
The link allows
The bq2052 can operate from the
batteries in the pack. The REF out-
put and an external FET provide a
simple, inexpensive voltage regula-
tor to supply power to the circuit
from the cells.
