Single-cell high-side protector for Li-Ion packs
The BQ298019RUGR is a single-cell battery protection IC from Texas Instruments, designed for Lithium Ion/Polymer chemistries. It integrates high-side protection against over-current, over-temperature, over/under-voltage, and short-circuit faults — all in an 8-X2QFN package measuring 1.5 mm per side.
Fault coverage and operating envelope
The device monitors a single Li-Ion or Li-Polymer cell and triggers protection on five fault types: over-current, over-temperature, over-voltage, under-voltage, and short-circuit. The operating temperature range spans -40°C to 85°C, covering the full industrial ambient band for portable and embedded battery packs. Packaged in an 8-XFQFN (supplied as 8-X2QFN), the footprint is 1.5x1.5 mm — suited for space-constrained designs like wearables, IoT nodes, and small-form-factor handhelds. Surface-mount assembly with Tape & Reel or Cut Tape options for prototype or volume builds.
