It accepts a supply voltage up to 28V, making it suitable for systems that need to survive unregulated adapters or 24V industrial rails without an external pre-regulator. The charge current is programmable up to 1.2A, and the IC includes over-voltage fault protection on the input. ## Package and mounting The 28V maximum supply voltage is the headline number for this part. It means you can connect a 24V industrial power supply or a 12V automotive rail directly to the input without a series regulator or a high-voltage buck front end — the charger handles it. The 1.2A maximum charge current is programmable, so you can set a lower current for smaller cells or for thermal management in the DFN package. At 1.2A the exposed pad needs a good thermal via stitch to the ground plane; without it the junction temperature climbs fast in a 85°C ambient. ## Package and footprint for the rework bench The MC34676BEPR2 comes in a 12-UFDFN with exposed pad, supplier device package DFN2514-12. That is a 2.5 mm × 1.4 mm body with a thermal pad underneath. The pad must be soldered to the PCB ground plane — a hot-air station or reflow oven is needed; hand-soldering with an iron is tricky because the pad is hidden. Orientation is marked by pin 1 chamfer on the top, but the package is tiny, so a magnifier or microscope is recommended for placement. ## Production status and sourcing It is ROHS3 compliant.","metaTitle":"MC34676BEPR2 Li-Ion Battery Charger IC, 28V Input, 1.2A","metaDescription":"MC34676BEPR2 single-cell Li-Ion charger IC, 28V max input, 1.2A programmable charge current, over-voltage protection, DFN2514-12 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Bulk","Interface":"USB","Mounting Type":"Surface Mount","Package / Case":"12-UFDFN Exposed Pad","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Voltage","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Battery Pack Voltage":"4.2V","Charge Current - Max":"1.2A","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Supply (Max)":"28V","Supplier Device Package":"DFN2514-12"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.01","stockQuantity":0,"priceTiers":[{"qty":75,"price":"$4.01000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3f258b01ead3fbfec61936a715e9c974.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the charge current capability of MC34676BEPR2?","answer":"The maximum charge current is 1.2A, and it is programmable — you can set a lower current for smaller cells or thermal management."},{"question":"Can MC34676BEPR2 charge two cells?","answer":"No, the MC34676BEPR2 is a single-cell charger only — it is designed for one Li-Ion cell with a 4.2V termination voltage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/nxp/MC34676BEPR2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/nxp/MC34676BEPR2 when reusing this data.
