It communicates over I²C and integrates over-voltage, over-current, and over-temperature fault protection — reducing the external supervisor BOM for portable and embedded systems. The 1-4 cell range covers single-cell handhelds up to 4S power-tool or medical packs. Multi-chemistry support means the same PCB layout works for Li-ion, LiFePO₄, or NiMH — no hardware spin for a chemistry swap. That flexibility saves a separate charger monitor variant per product line. ## I²C interface and fault protection The I²C interface lets the system MCU read cell voltages, temperature, and fault flags over a two-wire bus without dedicated ADC pins. Integrated over-voltage, over-current, and over-temperature protection means the monitor can trip independently — the host reads the fault register rather than needing a separate comparator chain. ## Industrial temperature range, active lifecycle ROHS3 compliant. Current production means it qualifies for new designs without supply-risk qualification. Housed in a 32-WFQFN with exposed pad (32-QFN 4x4 mm). Surface-mount only.","metaTitle":"TI BQ25700ARSNR Battery Monitor IC, I²C, 1-4 Cells","metaDescription":"TI BQ25700ARSNR multi-chemistry battery monitor.
