It reads temperature from both an internal sensor and an external diode-connected transistor, covering a sensing range of -64°C to 127°C with a maximum accuracy of ±3°C. The ±3°C accuracy is the worst-case limit across the full temperature range — for most of the operating band the typical error is tighter, but the BOM temperature-trip threshold should be set with this ±3°C guard band in mind. ## Signal chain and interface The internal topology combines a sigma-delta ADC, comparator, multiplexer, and register bank to digitize the sensor inputs and drive the fan output. Communication is over a 2-wire SMBus interface, so the part integrates directly with the system management bus on server, telecom, or industrial control boards without extra level shifting. The fan output is driven by the on-chip controller, and an alarm output signals overtemperature events to the host without polling. Surface-mount assembly with the 8-MSOP body keeps the component height low, suitable for mezzanine cards or blade servers where the thermal management IC must fit under an airflow shroud.","metaTitle":"EMC2101-R-ACZL-TR Fan Controller, ±3°C Accuracy, 8-MSOP","metaDescription":"Microchip Technology EMC2101-R-ACZL-TR fan controller and temperature monitor. ±3°C max accuracy, internal/external sensor, 2-wire SMBus.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Accuracy":"±3°C(Max)","Function":"Fan Control, Temp Monitor","Topology":"ADC (Sigma Delta), Comparator, Fan Control, Multiplexer, Register Bank","Output Fan":"Yes","Output Type":"2-Wire SMBus","Sensor Type":"Internal and External","Output Alarm":"Yes","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Sensing Temperature":"-64°C ~ 127°C","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"8-MSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.23","priceTiers":[{"qty":1,"price":"$1.23000","currency":"USD"},{"qty":25,"price":"$1.02840","currency":"USD"},{"qty":100,"price":"$0.96000","currency":"USD"},{"qty":2500,"price":"$0.96000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f8b32ade35612ce72a875ec3d3417f62.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/EMC2101-R-ACZL-TR/alternatives.json"},"ai":{"faq":[{"question":"What is the temperature accuracy of EMC2101-R-ACZL-TR?","answer":"The device guarantees a maximum temperature accuracy of ±3°C across the full -64°C to +127°C sensing range, covering both the internal and external diode sensor inputs."},{"question":"Is EMC2101-R-ACZL-TR RoHS compliant?","answer":"Yes, Microchip Technology lists it as ROHS3 compliant, meeting the current European Union restriction on hazardous substances."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/EMC2101-R-ACZL-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/EMC2101-R-ACZL-TR when reusing this data.
