What the over-voltage protection threshold means for your pack
The BQ294524DRVT is a dedicated Li-Ion battery protection IC from Texas Instruments, designed to monitor a 2 to 3 series-cell stack and trigger a fault when any cell exceeds its over-voltage threshold. This is the primary safeguard against charger runaway or cell imbalance that could push a cell past its safe voltage limit. It operates across -40°C to 110°C, covering the full thermal envelope of a battery pack in a charging bay or inside portable equipment. The 6-WSON (2x2 mm) package with exposed pad helps pull heat from the die into the PCB copper pour, keeping the protection circuit stable under sustained fault conditions.
Package and board-fit for the protection circuit
The 6-WDFN exposed pad package (6-WSON, 2x2 mm body) is a surface-mount footprint with a thermal pad underneath. Tape & Reel packaging is the standard delivery format for this part, suitable for automated pick-and-place assembly. Cut Tape is also available for prototyping or low-volume builds.
