摘要

Texas Instruments Inc.'s (TI) single-cell battery fuel gauge integrated circuit (IC), the BQ27505, is half the size of its predecessor. The 12-pin lithium battery capacity monitoring and reporting device resides in the system and comes in a 2.5×2×0.625mm WCSP package. It supports portable applications such as smart phones, digital cameras andrnMP3 players, where maintaining long battery life is critical for end users.
