The 10 A ceiling sets the inductor saturation current and the low-side FET Rds(on) budget — a 10 µH, 12 A-rated inductor and a pair of 30 V, 5 mOhm FETs keep the junction rise under 40°C at full load. ## Protection and temperature grade Built-in over-current and over-voltage fault protection reduces the need for external supervisory circuits — the charger latches off on a fault and requires a POR or enable toggle to restart. The 24 V maximum supply covers the typical 19 V to 20 V adapter rails used in 4-cell Li-ion systems.","metaTitle":"BQ24751BRHDRG4 Battery Charger IC, 10A Max, 2-4 Cells","metaDescription":"Texas Instruments BQ24751BRHDRG4 multi-chemistry battery charger IC. 10A max charge current, 2-4 cell support, 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)","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"28-VFQFN Exposed Pad","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":"18.048V (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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8135f200c7a6a446da28fe7b20158f16.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current setting for BQ24751BRHDRG4?","answer":"The maximum charge current is 10 A, programmable via an external sense resistor and the ISET pin.
