It monitors between 3 and 16 series cells, triggering a fault output when any cell exceeds the over-voltage threshold, drops below the under-voltage threshold, or the die temperature rises past the over-temperature limit. The 24-TSSOP package keeps the footprint small for space-constrained battery management boards in power tools, e-bikes, energy storage systems, and portable medical equipment. ## Protection coverage and temperature grade The fault-protection set covers over-voltage, under-voltage, and over-temperature. The operating temperature range is -40°C to 110°C (TA). ## Package and mounting Housed in a 24-TSSOP (0.173\", 4.40 mm width) surface-mount package. The supplier device package is also 24-TSSOP. ## Lifecycle and sourcing The BQ7721611PWR carries an active lifecycle status and is ROHS3 compliant.","metaTitle":"BQ7721611PWR Battery Protection IC, 3–16 Cells, 24-TSSOP","metaDescription":"TI BQ7721611PWR battery protection IC for 3–16 Li-ion cells.
