Preliminary bq2052  
Gas Gauge IC  
for Lithium Primary Cells  
communications link to an external  
Features  
General Description  
micro-controller. The link allows  
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.  
➤ Accurate measurement of avail-  
able capacity in Lithium primary  
batteries such as Lithium Sul-  
phur Dioxide and Lithium Man-  
ganese Dioxide  
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. The IC  
monitors a voltage drop across a  
sense resistor connected in series  
with the cells to determine dis-  
charge activity of the battery. The  
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.  
➤ Provides a low-cost battery moni-  
tor solution for pack integration  
- Complete circuit can fit less  
than 1 square inch of PCB  
space  
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.  
- Low operating current  
- Less than 100nA of data  
retention current  
➤ Single-wire communication inter-  
face (HDQ bus) for critical battery  
parameters  
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. The  
bq2052 supports a single-wire serial  
➤ Communicates remaining capac-  
ity with direct drive of LEDs in 3  
selectable modes  
➤ Measurements automatically  
compensated for discharge rate  
and temperature  
➤ 16-pin narrow SOIC
