Summary:
The Texas Instruments BQ2040 is a gas gauge IC designed for battery pack integration. It provides accurate charge measurement for NiCd, NiMH, and Li-Ion batteries.

Description:
The Texas Instruments BQ2040 is a gas gauge IC with an SMBus interface, intended for battery-pack or in-system installation to maintain an accurate record of available battery charge. It directly supports capacity monitoring for NiCd, NiMH, and Li-Ion battery chemistries.

Key features include support for the SBS v1.0 data set and a two-wire interface. The BQ2040 monitors the charge FET in Li-Ion pack protection circuits and can drive a four-segment LED display for remaining capacity indication. It operates from a 3.0V to 6.5V supply voltage and has an operating temperature range of 0°C to 70°C.

Designed for battery pack integration, the BQ2040 offers low operating current and a complete circuit that can fit on less than 3/4 square inch of PCB space. It supports SBS charge control commands for NiCd, NiMH, and Li-Ion batteries. Battery state-of-charge, remaining capacity, and remaining time are available over the serial link.

This IC is available in a 16-pin narrow SOIC package. It supports battery capacities ranging from a minimum of 800 mAh to a maximum of 10000 mAh and can manage 2-4 series cells.
