Single-cell gauge in a 15-bump DSBGA
The BQ27532YZFR-G1: Packaged in a 15-UFBGA, DSBGA (0.5 mm pitch, 15 bumps), it fits into space-constrained portable designs where the gauge sits directly on the battery pack or system board.
Rated for a single series cell (1-Cell) of Lithium Ion chemistry, the BQ27532YZFR-G1 monitors voltage, current, and temperature to report state-of-charge. The I²C interface lets a host MCU poll the gauge data without dedicated ADC channels — the gauge handles the coulomb counting and algorithm internally. The 15-DSBGA package (Supplier Device Package) demands a controlled reflow profile and X-ray inspection post-assembly; the 0.5 mm pitch limits hand rework.
