General Description
The bq2014 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 the 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.
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, dis-
charge, and self-discharge calcula-
tions to provide available charge in-
formation across a wide range of op-
erating conditions. Battery capacity
is automatically recalibrated, or
鈥渓earned,鈥?in the course of a dis-
charge cycle from full to empty.
The bq2014 includes a charge con-
trol output that controls an external
Fast Charge IC such as the bq2004.
Nominal Available Charge (NAC)
may be directly indicated using a
five-segment LED display.
The bq2014 supports a simple single-
line bidirectional serial link to an ex-
ternal processor (with a common
ground). The bq2014 outputs battery
information in response to external
commands over the serial link.
Internal registers include available
charge, temperature, capacity, bat-
tery voltage, battery ID, battery
status, and programming pin set-
tings. To support subassembly test-
ing, the outputs may also be con-
trolled. The external processor may
also overwrite some of the bq2014
gas gauge data registers.
The bq2014 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 V
CC
across a
greater number of cells.
