It uses the patented Impedance Track algorithm to report state-of-charge with better than 1% error across temperature and load — no need for a full learning cycle like coulomb-counting gauges. The I²C host interface lets the system MCU read remaining capacity, voltage, current, and temperature without a separate ADC. ## Single-cell Li-Ion only — check your pack topology This part is explicitly rated for 1 cell of Lithium Ion chemistry. It will not work with 2-series packs without external cell-balancing hardware. Sourced per RFQ against BOM quantity — confirm current lead time and pricing at quote time. ## 12-SON package with exposed pad Housed in a 12-VFDFN Exposed Pad package, supplier device package 12-SON (2.5x4 mm). Surface-mount only.","metaTitle":"BQ27541DRZR-G1 Texas Instruments Impedance Track™ Li-Ion","metaDescription":"BQ27541DRZR-G1 single-cell Li-Ion battery fuel gauge with Impedance Track™ algorithm.
