Battery protection for 2-4 series Li-ion packs
The BQ296226DSGR is a dedicated battery protection IC from Texas Instruments, designed to monitor and protect 2 to 4 series-connected lithium-ion cells against over-voltage faults. Operating across -40°C to 110°C, it suits portable electronics, power tools, and energy storage systems where the battery pack sees wide thermal swings. Housed in an 8-WSON (2x2) package with an exposed pad, the part is surface-mount ready for compact PCB layouts where thermal dissipation from the protection FET is managed through the pad.
