General Description
The bq2013H Gas Gauge IC is in-
tended for battery-pack installation to
maintain an accurate record of a bat-
tery’s available charge. The IC moni-
tors a voltage drop across a sense resis-
tor connected in series between the
negative battery terminal and ground
to determine charge and discharge ac-
tivity of the battery. The bq2013H is
designed for high cpaacity battery
packs used in high-discharge rate sys-
tems.
Battery self-discharge is estimated
based on an internal timer and tem-
perature sensor. Compensations for
battery temperature, rate of charge,
and self-discharge are applied to the
charge counter to provide available
capacity information across a wide
range of operating conditions. Initial
battery capacity, self-discharge rate,
display mode, and charge compensa-
tion are set using the PROG
pins.
Actual battery capacity is automati-
cally “learned” in the course of a dis-
charge cycle from full to empty.
Nominal available charge may be
directly indicated using a five-seg-
ment LED display. These segments
are used to graphically indicate
nominal available charge.
The bq2013H supports a simple
single-line bi-directional serial link to
an external processor (common
ground). The bq2013H outputs bat-
tery information in response to exter-
nal commands over the serial link. To
support battery pack testing, the
outputs may also be controlled by
command. The external processor
may also overwrite some of the
bq2013H gas gauge data registers.
The bq2013H may operate directly
from four nickel cells or three lead
acid.
With the REF output and an
external transistor, a simple, inexpen-
sive regulator can be built to provide
V
CC
from a greater number of cells.
Internal registers include available
charge, temperature, capacity, battery
ID,and battery status.
