For a system designer stacking error budgets, that ±1°C boundary is the number to use for thermal trip thresholds or compensation algorithms — the 25°C figure is fine for calibration but doesn't hold across temperature. ## 1.4V to 3.6V supply with one-shot and shutdown modes The sensor operates from a single 1.4V to 3.6V supply, covering 1.8V and 3.3V logic rails common in automotive ECUs. The one-shot feature lets the firmware command a single conversion and return to shutdown mode, drawing minimal quiescent current between reads — useful for battery-powered modules where every microamp counts. The output switch pin can be configured as a comparator or interrupt output, providing a hardware alert when temperature exceeds a programmable limit without polling the I²C bus. This offloads the host MCU in safety-critical thermal monitoring loops. ## SOT-5X3 package and active production status The SOT-5X3 package (SOT-563/SOT-666 footprint) is a small 6-lead surface-mount package, suitable for space-constrained PCB layouts. Tape & Reel and Cut Tape options are available for procurement flexibility. As an active Texas Instruments part with AEC-Q100 qualification, this sensor is a low-risk BOM line for automotive programs.","metaTitle":"TMP112AQDRLRQ1 Digital Temperature Sensor – AEC-Q100, I²C","metaDescription":"Texas Instruments TMP112AQDRLRQ1 digital local temperature sensor, ±0.3°C accuracy, 12-bit I²C/SMBus, -40°C to 125°C, AEC-Q100 qualified, SOT-5X3 package.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"One-Shot, Output Switch, Shutdown Mode","Resolution":"12 b","Output Type":"I²C/SMBus","Sensor Type":"Digital, Local","Mounting Type":"Surface Mount","Package / Case":"SOT-563, SOT-666","Product Status":"Active","Test Condition":"25°C (-40°C ~ 125°C)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.4V ~ 3.6V","Base Product Number":"TMP112","Operating Temperature":"-40°C~125°C","Supplier Device Package":"SOT-5X3","Accuracy - Highest (Lowest)":"±0.3°C (±1°C)","Sensing Temperature - Local":"-40°C~125°C","Sensing Temperature - Remote":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1400","priceTiers":[{"qty":1,"price":"$3.14000","currency":"USD"},{"qty":5,"price":"$2.91200","currency":"USD"},{"qty":10,"price":"$2.41900","currency":"USD"},{"qty":25,"price":"$2.01600","currency":"USD"},{"qty":50,"price":"$1.79200","currency":"USD"},{"qty":100,"price":"$1.70240","currency":"USD"},{"qty":500,"price":"$1.43360","currency":"USD"},{"qty":1000,"price":"$1.34400","currency":"USD"},{"qty":4000,"price":"$1.34400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a05a48bde6b76b9374184a73b28bd483.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TMP112AQDRLRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TMP112AQDRLRQ1 AEC-Q100 qualified and what does that mean for my design?","answer":"Yes, the TMP112AQDRLRQ1 is part of the Automotive, AEC-Q100 series. This qualification means the device has passed stress tests for high-temperature operation, ESD robustness, and extended life — it's intended for under-hood, chassis, and cabin applications where commercial-grade parts would fail."},{"question":"What is the closest pin-compatible alternative to TMP112AQDRLRQ1?","answer":"Within the TMP112 family, the base part number TMP112 (non-automotive grade) shares the same I²C interface, 12-bit resolution, and SOT-5X3 package. The key difference is the AEC-Q100 qualification — the 'AQ' suffix on this MPN guarantees automotive-grade reliability.
