bq2012  
Gas Gauge IC With  
Slow-Charge Control  
means of controlling charge based  
Features  
General Description  
on the battery's charge state.  
➤ Conservative and repeatable  
measurement of available charge  
in rechargeable batteries  
The bq2012 Gas Gauge IC is in-  
tended for battery-pack or in-system  
installation to maintain an accurate  
record of available battery charge.  
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.  
Nominal available charge may be di-  
rectly indicated using a five- or six-  
segment LED display. These seg-  
ments are used to graphically indi-  
cate nominal available charge.  
➤ Charge control output  
➤ Designed for battery pack inte-  
The bq2012 supports a simple  
single-line bidirectional serial link to  
an external processor (common  
ground). The bq2012 outputs battery  
information in response to external  
commands over the serial link.  
gration  
- 120µA typical standby current  
(self-discharge estimation mode)  
Self-discharge of NiMH and NiCd  
batteries is estimated based on an  
internal timer and temperature sen-  
sor. Compensations for battery tem-  
perature and rate of charge or dis-  
charge are applied to the charge,  
discharge, and self-discharge calcu-  
lations to provide available charge  
information across a wide range of  
operating conditions. Battery capac-  
ity is automatically recalibrated, or  
“learned,” in the course of a dis-  
charge cycle from full to empty.  
- Small size enables imple-  
Internal registers include available  
charge, temperature, capacity, battery  
ID, battery status, and programming  
pin settings. To support subassembly  
testing, the outputs may also be con-  
trolled. The external processor may  
also overwrite some of the bq2012 gas  
gauge data registers.

mentations in as little as  
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  
The bq2012 may operate directly  
from three or four cells. With the  
REF output and an external transis-  
tor, a simple, inexpensive regulator  
can be built to provide VCC across a  
greater number of cells.  
➤ Measurements compensated for  
current and temperature  
The bq2012 includes a charge con-  
trol output that, when used with  
other full-charge safety termination  
methods, can provide a cost-effective  
➤ Self-discharge compensation us-  
ing internal temperature sensor
