It integrates overcurrent, over/under voltage, short circuit, and overtemperature fault detection into a single 20-TSSOP package. The part is designed for consumer and industrial battery packs where a dedicated protector handles charge/discharge FET control and fault latch-off. ## Cell count flexibility and fault coverage With support for 3 to 5 series cells, this IC covers common Li-Ion pack configurations. The fault protection set — overcurrent, over/under voltage, short circuit, and overtemperature — covers the primary failure modes that a battery management system needs to catch before the pack is damaged. The operating temperature range of -40°C to 85°C suits portable tools, e-bikes, UPS backup, and outdoor telecom battery enclosures. ## Package and mounting The BQ7790500PWR comes in a 20-TSSOP package (4.40 mm body width) for surface-mount assembly. It is offered in Tape & Reel (TR) or Cut Tape (CT) options, which affects pick-and-place feeder setup and minimum order quantity. The ROHS3 compliance is confirmed, so no lead-free process exemption is needed.","metaTitle":"TI BQ7790500PWR Battery Protection IC, 3-5 Cell Li-Ion","metaDescription":"Texas Instruments BQ7790500PWR Li-Ion battery protection IC for 3-5 cells.
