# BQ27220YZFR (Component) ## Description Battery Battery Monitor IC Lithium Ion 9-DSBGA The BQ27220YZFR is a highly integrated single-cell battery fuel gauge IC developed for rechargeable lithium-ion and lithium-polymer battery applications. The device utilizes Texas Instruments’ Impedance Track™ algorithm to provide highly accurate battery capacity measurement, state-of-charge estimation, runtime prediction, and battery health monitoring across varying load and temperature conditions. The device is designed for compact portable electronics, wearable devices, IoT products, handheld instruments, and low-power embedded systems requiring precise battery monitoring and extended operating life. The BQ27220YZFR supports system-side fuel gauging without requiring battery pack-side electronics, simplifying battery integration and reducing overall system cost. The fuel gauge continuously monitors battery voltage, current, and temperature to estimate available capacity, remaining runtime, full charge capacity, and state-of-health information. Integrated low-power operation enables ultra-low standby current consumption suitable for always-on battery-powered products. Communication with the host processor is implemented through a standard I²C interface, allowing configuration access, telemetry reporting, and battery parameter monitoring. The device also integrates protection and alert functionality through programmable interrupt outputs and battery condition monitoring features. The BQ27220YZFR is optimized for use with single-cell lithium-based chemistries and supports learning cycles for adaptive battery characterization over product lifetime. Internal data flash memory stores battery profile information and calibration parameters to improve long-term gauging accuracy. The device is supplied in a compact lead-free wafer chip-scale package suitable for space-constrained PCB designs and portable electronics requiring minimal footprint and low-profile assembly.
