It is designed for the secondary protection path in a battery management system — it does not integrate charge/discharge FET control or cell balancing, so it sits alongside a primary protection IC or analog front-end to add a redundant over-voltage trip. The -40°C to 110°C operating range covers the full automotive and industrial temperature envelope, making it suitable for battery packs in power tools, e-bikes, energy storage, and portable equipment that sees elevated internal temperatures. ## Package and board-fit for space-constrained designs Surface-mount assembly with the exposed pad soldered to a thermal land on the PCB improves heat transfer from the IC to the board copper, which matters when the protection IC is mounted near high-discharge cells that raise the local ambient.","metaTitle":"TI BQ296228DSGR Battery Protection IC, 2-4 Cell Li-Ion","metaDescription":"Texas Instruments BQ296228DSGR Li-ion battery protection IC for 2-4 series cells.
