The BQ2092SN-A311 from Texas Instruments is a Gas Gauge IC with an SMBus-like 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 features a two-wire SMBus-like interface and supports SBData charge control commands. Measurements are compensated for current and temperature, and it offers programmable self-discharge and charge compensation. The device operates within a 3.0V to 5.5V supply voltage range and has a typical operating current of 120µA.
Designed for battery pack integration, the BQ2092SN-A311 is housed in a 16-pin narrow SOIC package, enabling implementations in compact spaces. It can indicate battery state-of-charge and capacity remaining over a serial link, and can directly drive a four-segment LED display to graphically depict battery status.
The device estimates battery self-discharge based on an internal timer and temperature sensor, along with user-programmable rate information stored in external EEPROM. It automatically recalibrates battery capacity during a full discharge cycle. The BQ2092SN-A311 may operate directly from three nickel chemistry cells, or with an external regulator for other configurations.
