It integrates overcurrent, over/under voltage, short-circuit, and overtemperature fault protection into a single 20-TSSOP package. The device operates over the industrial temperature range of -40°C to 85°C, suiting it for portable tools, e-bikes, energy storage, and other multi-cell Li-Ion applications where a dedicated protection controller is required rather than a discrete comparator-and-FET solution. ## Package and mounting The 20-TSSOP package (4.40 mm body width) is a surface-mount footprint common in portable electronics. The Tube shipping medium is typical for prototype and low-to-medium volume assembly; for higher volumes the part is also available in Tape & Reel under a different order code. The -40°C to 85°C operating range covers the majority of industrial and consumer battery applications without requiring automotive-grade qualification.","metaTitle":"BQ7790522PW Battery Protection IC, 3-5 Cell Li-Ion, 20-TSSOP","metaDescription":"TI BQ7790522PW battery protection IC for 3-5 series Li-Ion cells.
