It integrates over-current, over-temperature, over-voltage, and short-circuit fault protection for safe charging in industrial and portable equipment. ## 10 A charge current and thermal design The 10 A maximum charge current sets the power-stage requirements: the external MOSFETs, inductor, and sense resistor must be sized for continuous 10 A with headroom. Supply voltage is rated up to 24 V, covering common adapter rails for 2-4 cell packs. The constant-current charging mode is programmable via an external resistor. The BQ24742RHDT carries an obsolete lifecycle status.","metaTitle":"BQ24742RHDT Li-Ion Battery Charger IC, 10A Max, Obsolete","metaDescription":"Texas Instruments BQ24742RHDT Li-Ion/Polymer battery charger IC, 2-4 cells, 10A max charge current, 24V supply, 28-VQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Obsolete","Number of Cells":"2 ~ 4","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature, Over Voltage, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24742","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":"$1.0000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/54a7660605cac4c809bd08966b39dcf0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current of BQ24742RHDT?","answer":"The maximum charge current is 10 A, programmable via an external resistor.
