The BQ2040SN-D111TR from Texas Instruments 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.
This IC utilizes the System Management Bus v1.0 (SMBus) protocol and supports Smart Battery Data (SBData) commands, including charge control functions. Battery state-of-charge, remaining capacity, and chemistry are available over the serial link. A four-segment LED display can be driven directly to graphically depict battery charge status in 25% increments.
Designed for battery pack integration, the BQ2040SN-D111TR operates with low current consumption and its complete circuit can fit on less than 3/4 square inch of PCB space. It monitors the charge FET in Li-Ion pack protection circuits and estimates battery self-discharge based on an internal timer and temperature sensor.
The device is supplied in a 16-pin narrow SOIC package and is suitable for surface mount applications. It operates within a temperature range of 0°C to 70°C.
