The BQ2040SN-D111 from Texas Instruments is a gas gauge IC designed for battery pack integration, providing accurate measurement of available charge for NiCd, NiMH, and Li-Ion batteries. It utilizes the System Management Bus (SMBus) v1.0 protocol and supports Smart Battery Data (SBData) commands for reporting battery state-of-charge, remaining capacity, and chemistry.
This IC features a four-segment LED display driver for direct indication of remaining battery capacity in 25% increments. It operates within a temperature range of 0°C to 70°C and requires a supply voltage between 3.0V and 6.5V. The device is housed in a 16-pin SOIC package and supports surface mount installation.
Designed for battery pack integration, the BQ2040SN-D111 monitors charge FETs in Li-Ion protection circuits and supports SBS charge control commands. It estimates battery self-discharge and automatically recalibrates battery capacity during discharge cycles. The device is suitable for applications requiring precise battery charge monitoring and indication.
