System-Side Battery Gauge Extends Run Time in Smart Phones and Other Portable Devices

The new bq27500 system-side battery fuel gauge from Texas Instruments accurately predicts battery run time in single-cell handheld electronic devices. Featuring TI’s patented Impedance Track technology, the IC maintains accuracy for the entire life of the battery under all conditions, reserves energy to save data and never sacrifices run time.

KEY FEATURES • Resides on the system’s main board and manages an embedded or removable battery pack • Microcontroller peripheral provides accurate battery fuel gauging • TI’s Impedance Track technology   - Models the battery discharge curve for accurate time-to-empty predictions - Automatically adjusts for battery aging, battery self discharge and temperature/rate inefficiencies   KEY APPLICATIONS • Smart phones • Portable navigation systems • Portable audio and media players • Portable medical and industrial devices • Any single-cell Li-Ion application
