It integrates over-current and over-voltage fault protection, so the system can shut down the charge path without relying on an external supervisor. ## Charge current and pack voltage — the real BOM limits The maximum charge current of 10 A is programmable via an external sense resistor and the ISET pin — the actual current you can sustain depends on the thermal dissipation in the 28-VFQFN package and the board's copper pour on the exposed pad. The maximum battery pack voltage is 18.04 V, which covers 4-series Li-ion (16.8 V) and 4-series LiFePO4 (14.6 V) packs with margin, but not 5-series stacks. Supply voltage can go up to 24 V, so the input can be a 19 V laptop adapter or a 24 V industrial rail without an extra pre-regulator. ## Package and footprint — what the rework tech needs to know The 28-VFQFN with exposed pad (5 mm × 5 mm) is a surface-mount package that requires a hot-air or reflow station to remove — not a field-swap part unless you carry a hot-air pencil and solder paste. Cut Tape works for prototypes or small repair runs.","metaTitle":"BQ24751ARHDR Battery Charger IC, 10A Max, 28-VFQFN","metaDescription":"Texas Instruments BQ24751ARHDR multi-chemistry battery charger IC. 10A max charge current, 18.04V pack voltage, over-current/over-voltage protection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"28-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"2 ~ 4","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Voltage","Battery Chemistry":"Multi-Chemistry","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24751","Battery Pack Voltage":"18.04V (Max)","Charge Current - Max":"10A","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"-","Voltage - Supply (Max)":"24V","Supplier Device Package":"28-VQFN (5x5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.1770","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/97ebf60039faa392fa6d00ccc811a84b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current for BQ24751ARHDR?","answer":"The maximum programmable charge current is 10 A.
