The BQ2040SN-C408 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. It can drive a four-segment LED display for remaining capacity indication in 25% increments.
The BQ2040SN-C408 operates from a 3.0V to 6.5V supply voltage and has an operating temperature range of 0°C to 70°C. It is housed in a 16-pin SOIC package and is designed for surface mount integration. The device monitors charge FET in Li-Ion pack protection circuits and supports SBS v1.0 data set and a two-wire interface.
