The BQ27505YZGT-J2 from Texas Instruments is a system-side battery fuel gauge IC specifically designed for 1-series Lithium Ion and Li-Polymer battery applications. It resides on the system main board and works with both embedded and removable battery packs, utilizing PACK+, PACK-, and T battery terminals.
This fuel gauge IC features the patented Impedance Track™ algorithm, which accurately models the battery discharge curve for reliable time-to-empty predictions. It automatically adjusts for battery aging, self-discharge, and temperature/rate inefficiencies. The device provides accurate battery fuel gauging, an internal temperature sensor for battery temperature reporting, and warnings for low battery conditions.
Key features include an I2C communication interface operating at 400 kHz, suitable for connection to a system microcontroller. It supports a battery capacity range from 300 mAh to 8000 mAh and operates within a temperature range of -40°C to 85°C. The BQ27505YZGT-J2 is supplied in a compact 12-pin DSBGA (YZG) package, measuring 3.9375 mm².
Applications for this fuel gauge IC include smartphones, PDAs, digital still and video cameras, handheld terminals, and MP3 or multimedia players where precise battery monitoring is crucial.
