That 24V input ceiling means you can run it off a common 19V notebook adapter or a 24V industrial supply, but not a 48V telecom rail — anything above 24V needs a pre-regulator or a different charger IC. The multi-chemistry support lets the same BOM handle Li-ion, Li-Pol, or NiMH packs by adjusting the charge algorithm, which simplifies inventory if your product ships with different battery types. ## Fault protection and programmable current — bench-level reliability Integrated over-current and reverse-battery protection means the charger can survive a pack plugged in backwards or a shorted cell without letting the magic smoke out. On the repair bench, that translates to fewer blown upstream FETs and a board that comes back alive after a battery swap. The charge current is constant and programmable, so you set the rate with a resistor or firmware — no external current-sense amp needed. ## Industrial temperature grade and active lifecycle It is not AEC-Q100 qualified, so skip it for under-hood automotive. That removes the single-source risk for a production BOM, though as with any active IC, availability and pricing fluctuate — confirmed at quote time.","metaTitle":"BQ24730RGFRG4 Battery Charger IC, 24V Input, 3-4 Cell","metaDescription":"Texas Instruments BQ24730RGFRG4 multi-chemistry battery charger IC. 24V max supply, 3-4 cell support, over-current and reverse-battery protection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Series":"-","Interface":"-","Packaging":"Tape & Reel (TR)","Part Status":"Obsolete","Manufacturer":"Texas Instruments","Mounting Type":"Surface Mount","Package / Case":"40-VFQFN Exposed Pad","Number of Cells":"3 ~ 4","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Reverse Battery","Battery Chemistry":"Multi-Chemistry","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24730","Battery Pack Voltage":"16.8V","Charge Current - Max":"-","Operating Temperature":"-40°C ~ 85°C (TA)","Programmable Features":"Current","Voltage - Supply (Max)":"24V","Supplier Device Package":"40-VQFN (7x5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9ca25da1181ca26ba5060b64fcb5b085.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What battery chemistries and cell counts does BQ24730RGFRG4 support?","answer":"It supports multi-chemistry types — Li-ion, Li-Pol, NiMH, etc. — and handles 3 to 4 series cells.
