discharge based on an internal

General Description  
timer and temperature sensor and  
The bq2040 Gas Gauge IC With  
user-programmable rate informa-  
SMBus Interface is intended for  
tion stored in external EEPROM.  
battery-pack or in-system installa-  
The bq2040 also automatically re-  
tion to maintain an accurate record  
calibrates or “learns” battery capac-  
of available battery charge. The  
ity in the full course of a discharge  
bq2040 directly supports capacity  
cycle from full to empty.  
Provides accurate measurement  
of available charge in NiCd,  
NiMH, and Li-Ion batteries  
Supports SBS v1.0 data set and  
two-wire interface  
monitoring for NiCd, NiMH, and Li-  
Monitors charge FET in Li-Ion  
Ion battery chemistries.  
The bq2040 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 configu-  
rations.  
pack protection circuit  
The bq2040 uses the System Man-  
agement Bus v1.0 (SMBus) protocol  
and supports the Smart Battery  
Data (SBData) commands. The  
bq2040 also supports the SBData  
charge control functions. Battery  
state-of-charge, remaining capacity,  
remaining 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.  
Designed for battery pack inte-  
gration  
- Low operating current  
- Complete circuit can fit on less  
than ¾ square inch of PCB  
space  
An external EEPROM is used to  
program initial values into the  
bq2040 and is necessary for proper  
operation.  
Supports SBS charge control  
commands for NiCd, NiMH, and  
Li-Ion  
Drives a four-segment LED dis-  
play for remaining capacity
