Supplied in Tube packaging (the listed package format), which is typical for prototype quantities and low-volume production; for higher volumes, verify reel availability with your Microchip channel partner. ## Compliance and sourcing The TC647BEOA is ROHS3 Compliant per Microchip's declaration — no RoHS exemption conflicts for EU-market builds. No stock-holding claim — availability verified per inquiry.","metaTitle":"Microchip TC647BEOA Fan Controller, 3V-5.5V, 8-SOIC","metaDescription":"Active-production Microchip TC647BEOA BLDC fan speed controller. 3V-5.5V supply, pre-driver low-side output, -40°C to +85°C.","metaKeywords":null},"attributes":{"series":"FanSense™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"FanSense™","Package":"Tube","Function":"Controller - Speed","Interface":"Parallel","Applications":"Fan Controller","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Motor Type - AC, DC":"Brushless DC (BLDC)","Output Configuration":"Pre-Driver - Low Side","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.63","priceTiers":[{"qty":1,"price":"$1.63000","currency":"USD"},{"qty":25,"price":"$1.50000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ab13d94fb9eee909703ea802b4436d61.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TC647BEOA/alternatives.json"},"ai":{"faq":[{"question":"What is the TC647BEOA's FanSense™ series used for?","answer":"The FanSense™ series from Microchip integrates speed-control and fault-detection logic for brushless DC fans, typically in thermal-management subsystems for power supplies, computing, and industrial equipment."},{"question":"What compliance documentation does Microchip provide for TC647BEOA?","answer":"Microchip declares ROHS3 Compliant status for the TC647BEOA.
