It communicates over an I²C interface, making it a drop-in for portable designs that already have a two-wire bus available. The 12-DSBGA package (0.50 mm pitch, no exposed pad) keeps the footprint under 3 mm², which suits space-constrained PCBs in handheld instruments, medical disposables, and IoT endpoints. ## Temperature range and application fit The Impedance Track™ algorithm compensates for temperature-dependent impedance shifts, so the reported capacity stays within a few percent across the range. ## Sourcing and lifecycle posture The base product number BQ27505 covers several package and tape variants; the -J2 suffix denotes the specific 12-DSBGA reel configuration.","metaTitle":"BQ27505YZGR-J2 Battery Monitor, Impedance Track™, I²C","metaDescription":"TI BQ27505YZGR-J2 single-cell Li-ion battery monitor with Impedance Track™ algorithm.
