Quantities are lot-specific and confirmed at RFQ — no stock-holding claim. The BQ24741RHDR is a Li-Ion/Polymer battery charger IC supporting 2 to 4 series cells. The maximum battery pack voltage is 18.048 V, which sets the ceiling for the cell stack — a 4S pack with 4.2 V/cell termination lands at 16.8 V, well within this limit. Charge current is constant and programmable up to 10 A. The 10 A ceiling means this IC can handle high-capacity packs (e.g., 5000 mAh cells at a 2C rate) without needing an external pass FET for current scaling. Fault protection covers overcurrent, overtemperature, overvoltage, and short circuit. The overvoltage threshold is tied to the battery pack voltage limit — if a cell fails open, the charger shuts down before the remaining cells exceed their absolute max. Supply voltage max is 24 V. A 3S or 4S pack charged from a 19 V laptop adapter or a 24 V industrial rail is within the input range — no external pre-regulator needed. ## Package and temperature grade Housed in a 28-VFQFN Exposed Pad (5x5 mm, supplier package 28-VQFN). The datasheet layout recommendation for the pad via pattern should be followed to keep junction temperature within the -40°C to 125°C operating range. Surface mount, supplied in Tape & Reel. The reel quantity is not specified here, but the 5x5 mm QFN footprint is standard for pick-and-place — no special feeder or nozzle is required.","metaTitle":"BQ24741RHDR Texas Instruments Battery Charger IC, 10A","metaDescription":"BQ24741RHDR from Texas Instruments is an obsolete Li-Ion/Polymer battery charger IC. 10A max charge current, 2-4 cells, 28-VFQFN.
