It reads the local die temperature across a -40°C to 125°C range and reports it over an I²C/SMBus interface, while the integrated fan control loop can drive a cooling fan directly based on the temperature reading. The ±12% accuracy is typical for a general-purpose system monitor — adequate for server chassis, telecom line cards, and industrial controller boards where the goal is to trigger a fan ramp or an over-temperature warning, not to log precise thermal data. ## Supply range and temperature grade — where it fits The 2.8 V to 5.75 V supply range means the DS1780E+T&R can run from a standard 3.3 V or 5 V rail without an extra regulator. The -40°C to 125°C operating temperature covers the full industrial range and the lower end of automotive under-hood environments, so it is a natural fit for outdoor telecom cabinets, motor-drive enclosures, and power-supply base stations where the ambient can swing from a cold start to a hot plenum. ## Lifecycle and sourcing The DS1780E+T&R is listed as Active with ROHS3 compliance. For a BOM line that needs a thermal monitor with integrated fan control, this part carries no LTB risk and can be specified into new designs with confidence.","metaTitle":"DS1780E+T&R CPU Peripheral Monitor, ±12% Accuracy, 24-TSSOP","metaDescription":"DS1780E+T&R is an active CPU peripheral monitor with internal sensor, fan speed control, I²C/SMBus output, ±12% accuracy, -40°C to 125°C range. 24-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Accuracy":"±12%","Function":"Thermal Monitor, CPU Peripherals","Topology":"ADC (Sigma Delta), Comparator, Fan Speed Control, Register Bank","Output Fan":"Yes","Output Type":"I²C/SMBus","Sensor Type":"Internal","Output Alarm":"No","Mounting Type":"Surface Mount","Package / Case":"24-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.8V ~ 5.75V","Sensing Temperature":"-40°C ~ 125°C","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"24-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.24","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.24000","currency":"USD"},{"qty":10,"price":"$5.60100","currency":"USD"},{"qty":25,"price":"$5.29480","currency":"USD"},{"qty":100,"price":"$4.58890","currency":"USD"},{"qty":250,"price":"$4.35360","currency":"USD"},{"qty":500,"price":"$3.90648","currency":"USD"},{"qty":1000,"price":"$3.29462","currency":"USD"},{"qty":2000,"price":"$3.12989","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/DS1780.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does DS1780E have fan speed control?","answer":"Yes, the DS1780E integrates fan speed control logic as part of its CPU peripheral monitor function.
