bq2092  
Gas Gauge IC with SMBus-Like Interface

Features  
General Description  
discharge based on an internal  
timer and temperature sensor and  
Provides accurate measure-  
ment of available charge in  
The bq2092 Gas Gauge IC With  
SMBus-Like Interface is intended  
for battery-pack or in-system instal-  
lation to maintain an accurate  
record of available battery charge.  
The bq2092 directly supports capac-  
ity monitoring for NiCd, NiMH, and  
Li-Ion battery chemistries.  
user-programmable rate informa-  
tion stored in external EEPROM.  
The bq2092 also automatically  
recalibrates or “learns” battery  
capacity in the full course of a  
discharge cycle from full to empty.  
NiCd, NiMH, and Li-Ion re-  
chargeable batteries  
Supports SBData charge con-  
trol commands for Li-Ion,  
NiMH, and NiCd chemistries  
The bq2092 may operate directly  
from three nickel chemistry cells.  
With the REF output and an exter-  
nal transistor, a simple, inexpensive  
regulator can be built to provide VCC  
for other battery cell configurations.  
Designed for battery pack inte-  
gration  
The bq2092 uses the SMBus proto-  
col that supports many of the Smart  
Battery Data (SBData) commands.  
The bq2092 also supports SBData  
charge control. Battery state-of-  
charge, capacity remaining, remain-  
ing time and chemistry are available  
over the serial link. Battery-charge  
state can be directly indicated using  
a four-segment LED display to  
graphically depict battery full-to-  
empty in 25% increments.  
- 120µA typical operating  
current  
An external EEPROM is used to  
program initial values into the  
bq2092 and is necessary for proper  
operation.

implementations in as little as
