It accepts a supply voltage up to 24 V and integrates over-current and over-voltage fault protection, reducing external supervisor count on the power path. ## Charge current and thermal budget The 10 A max charge current sets the power-stage MOSFET and inductor selection — at 18 V battery pack voltage that is 180 W delivered. At high charge rates the board copper area becomes the limiting thermal resistance. ## Fault protection and voltage ceiling Built-in over-current and over-voltage protection covers the common failure modes on a multi-cell charger — no need for an external comparator or supervisor on the output rail. The 18.048 V max battery pack voltage matches a 4-series Li-ion stack (4.2 V/cell × 4 = 16.8 V nominal, 18.048 V is the charge ceiling). The 24 V supply max leaves headroom for a 19 V to 20 V adapter common in notebook and industrial battery designs. ## Package and sourcing The supplier device package is 28-VQFN (5x5 mm).","metaTitle":"BQ24753RHDT Multi-Chemistry Battery Charger IC, 10A","metaDescription":"Texas Instruments BQ24753RHDT multi-chemistry battery charger, 10A max charge current, 2~4 cells, -40°C to 125°C.","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":"BQ24753","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":"$10.5579","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/28dbded2890d302df3e67d44142dbe47.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does BQ24753RHDT support charging 4-cell Li-Ion batteries?","answer":"Yes.
