Single-cell Li-ion fuel gauge with Impedance Track™
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.
The Impedance Track™ algorithm compensates for temperature-dependent impedance shifts, so the reported capacity stays within a few percent across the range.
The base product number BQ27505 covers several package and tape variants; the -J2 suffix denotes the specific 12-DSBGA reel configuration.
