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. Availability and pricing are confirmed against an RFQ; no stock-holding claim is made here.","metaTitle":"BQ27530YZFR-G1 Battery Monitor, Impedance Track","metaDescription":"Texas Instruments BQ27530YZFR-G1 single-cell Li-Ion battery monitor with Impedance Track, I²C interface, 15-DSBGA, -40°C to 85°C.

However, the datasheet should be consulted for any temperature-sensing options if pack-level temperature monitoring is needed."},{"question":"Is BQ27530YZFR-G1 compatible with 2-cell batteries?","answer":"No — this part is specified for single-cell (1-cell) Li-Ion battery monitoring only.
