Single-cell Li-Ion monitor with Impedance Track
The BQ27530YZFR-G1 from Texas Instruments is a single-cell Lithium-Ion battery monitor that uses the Impedance Track algorithm to deliver state-of-charge and state-of-health estimates without the need for a full charge-discharge learning cycle. It communicates over an I²C interface, making it a drop-in fit for portable electronics, medical devices, and industrial handhelds where the host MCU already has an I²C bus.
Industrial temperature rating — design margin for outdoor gear
The temperature range matches the operating envelope of most Li-Ion cells, so the monitor tracks accurately across the full usable window of the chemistry.
15-DSBGA package — tight footprint, tight layout
The 15-DSBGA (0.5 mm pitch, 2.0 x 2.2 mm body) saves board area but demands a well-planned PCB fan-out and a controlled reflow profile. The small solder balls need a clean stencil aperture — a 0.25 mm via-in-pad design is typical for this class of package. Moisture sensitivity level (MSL) is not listed here, but a bake cycle before rework is standard practice for any BGA-style part.
