Texas Instruments BQ20Z655DBTR-R1 is a sophisticated battery fuel gauge IC from the Impedance Track™ series. This multi-function controller is engineered for Lithium Ion and Polymer battery packs, supporting configurations of 2 to 4 cells. It features an SMBus interface for communication and provides comprehensive fault protection, including over current, over temperature, over/under voltage, and short circuit detection. The BQ20Z655DBTR-R1 utilizes advanced Impedance Track™ technology for accurate state-of-charge (SOC) and state-of-health (SOH) reporting, even across a wide range of operating temperatures from -40°C to 85°C (TA). Its 44-TSSOP package is supplied in tape and reel, suitable for surface mount applications. This component is widely integrated into portable electronics, medical devices, and industrial equipment requiring precise battery monitoring and management.
