The BQ27742-G1 is a single-cell Li-Ion battery fuel gauge designed by Texas Instruments, utilizing patented Impedance Track,Ñ¢ technology for accurate battery capacity and runtime predictions. It features a precision 16-bit high-side coulomb counter that operates with low-value sense resistors ranging from 5 m,Ѷ to 20 m,Ѷ. The device includes both external and internal temperature sensors for comprehensive battery temperature monitoring and supports data logging for lifetime and current data. This fuel gauge integrates a high-side NMOS protection FET drive, eliminating the need for a separate protection circuit. It offers hardware-based safety features, including overvoltage, undervoltage, and overcurrent protection, as well as short-circuit detection. Communication with the host system is facilitated through I¬=C and HDQ interfaces. The BQ27742-G1 is packaged in a compact 15-ball NanoFree,Ñ¢ DSBGA, making it suitable for space-constrained applications such as smartphones, tablets, and portable gaming devices.
