The Texas Instruments BQ27505YZGT-J3 is a system-side battery fuel gauge IC for 1-series Li-Ion and Li-Polymer battery applications. It resides on the system main board and works with both embedded and removable battery packs.
This IC provides accurate battery fuel gauging using the patented Impedance Track™ technology, which models the battery discharge curve for precise time-to-empty predictions. It automatically adjusts for battery aging, self-discharge, and temperature/rate inefficiencies. Key features include an internal temperature sensor for battery temperature reporting, battery low interrupt warnings, and configurable state of charge (SOC) interrupts.
The BQ27505YZGT-J3 communicates via a 400-kHz I²C interface, connecting to the system microcontroller. It supports a battery capacity range from 300 mAh to 8000 mAh and operates within an ambient temperature range of -40°C to 85°C.
Packaged in a 12-pin DSBGA (YZG), this fuel gauge is suitable for applications such as smartphones, PDAs, digital cameras, handheld terminals, and MP3 players.
