That means it remains a valid choice for new designs and ongoing production without forced requalification.","metaTitle":"ADM1027ARQ dBCool Fan Controller, Temp Monitor, ±1°C","metaDescription":"ADM1027ARQ dBCool remote thermal controller from ON Semiconductor. ±1°C accuracy, SMBus output, 0°C to 105°C range, 24-SSOP.","metaKeywords":null},"attributes":{"series":"dBCool®","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"dBCool®","Package":"Bulk","Accuracy":"±1°C","Function":"Fan Control, Temp Monitor","Topology":"ADC, Comparator, Fan Speed Counter, Multiplexer, Register Bank","Output Fan":"Yes","Output Type":"SMBus","Sensor Type":"Internal and External","Output Alarm":"No","Mounting Type":"Surface Mount","Package / Case":"24-SSOP (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Sensing Temperature":"0°C ~ 105°C, External Sensor","Operating Temperature":"0°C ~ 105°C","Supplier Device Package":"24-QSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.64","stockQuantity":0,"priceTiers":[{"qty":114,"price":"$2.64000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f2b110a5034f146d0198b6be9e36e8ce.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ADM1027ARQ compatible with SMBus?","answer":"Yes, the output type is SMBus.
