If your rail sits at 24 V nominal with a 10 % tolerance, you have margin; a 28 V rail at full tolerance leaves no headroom and risks hitting the abs-max. Multi-chemistry support means the same IC handles Li-ion, Li-Po, NiMH, and NiCd cells without swapping the controller — useful when a product line spans chemistries or when field-replacement packs vary. The charger algorithm adjusts the termination voltage and charge profile per chemistry, but the external passives (sense resistor, inductor, FETs) still need to be sized for the worst-case current of the target pack. ## Industrial temperature range and package — where it fits A stencil and reflow profile matching the datasheet land pattern is the reliable path for production. ## Active production — sourcing without the scavenger hunt It is a current-production part available through authorized and independent channels alike.","metaTitle":"TI BQ24703RHDR Battery Charger IC, 28V, Multi-Chemistry","metaDescription":"Texas Instruments BQ24703RHDR — active-production multi-chemistry battery charger IC, 28V max supply, -40 to 85°C, 28-VQFN package.","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":"-","lifecycle_stage":"eol_hot","Fault Protection":"-","Battery Chemistry":"Multi-Chemistry","Current - Charging":"-","Base Product Number":"BQ24703","Battery Pack Voltage":"-","Charge Current - Max":"-","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"28V","Supplier Device Package":"28-VQFN (5x5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0480","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/033374a2dfc4db735f78429d1a9e7208.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24703RHDR/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation does Texas Instruments provide for BQ24703RHDR?","answer":"Texas Instruments provides RoHS and REACH compliance data for the BQ24703RHDR through its standard documentation portal.
