The 24 V max supply voltage covers common notebook and portable equipment rails — 2S through 4S Li-ion packs are within reach without an external pre-regulator. ## Fault protection set and temperature grade On-chip fault protection covers overcurrent, overvoltage, and short-circuit conditions — the charger enters a safe state without relying on the host controller. Housed in a 28-WFQFN with exposed pad (4x4 mm body), the BQ24780SRUYR uses the pad as the primary thermal path.","metaTitle":"BQ24780SRUYR TI Battery Charger IC, SMBus, 1-4 Cells","metaDescription":"Texas Instruments BQ24780SRUYR multi-chemistry battery charger IC, SMBus interface, 1-4 cells, 24V max supply, 28-WQFN.
