BQ298012RUGR

BQ298012RUGR is a Texas Instruments battery fuel gauge IC (gas gauge) for single‑cell Li‑ion/Li‑polymer packs. It monitors pack voltage, current (via an external sense resistor), and temperature, and uses coulomb counting to estimate state of charge (SOC) and remaining capacity. It provides status and control information over a serial interface (SMBus/I2C‑compatible) and reports faults/alerts for battery protection. The device typically requires external support components (current sense path, temperature sensor/NTC, and a host controller to read SOC and health data). The RUGR suffix denotes packaging/packaging options (RoHS-compliant, tape‑and‑reel variant; exact physical package varies). Applications include portable devices, wearables, and other battery-powered products where accurate SOC estimation and battery health monitoring are important. For exact features, electrical specs, pinout, and package details, refer to the TI bq298012 datasheet and product page.

BQ298012RUGR is TI’s battery monitor/gas gauge IC. There is no published exact drop-in cross‑reference. To find substitutes, use TI’s Cross Reference tool with your specs (cell count, interface, voltage). Closest TI families are BQ76920/76930/76940 (multi‑cell gauges) and the BQ29700 family (cell protection/gauging). For exact equivalents, contact TI or distributors for a cross‑reference.
