Active production, automotive-grade temperature sensing
The LMT85QDCKRQ1 is an active-production analog local temperature sensor from Texas Instruments, qualified to AEC-Q100 automotive grade. It senses the local die temperature across the full -50°C to 150°C range and outputs a linear analog voltage with a slope of 8.2mV/°C. The ±2.7°C accuracy (highest) covers the operating range without needing calibration, which simplifies BOM qualification for engine-control or cabin-sensing loops where the absolute temperature matters more than the fine resolution.
Supply flexibility and deployment envelope
The 1.8V floor allows battery-level operation during cranking conditions. The -50°C to 150°C operating range covers the full under-hood temperature band. AEC-Q100 Grade 0 parts typically cover -40°C to 150°C; this sensor extends the cold side to -50°C, relevant for cold-start testing or arctic-environment deployments.
Housed in a 6-pin SC-70 (SOT-363) package, supplier device package designation SC-70. The 0.65mm pitch and 2.0mm x 2.1mm footprint fit dense PCB layouts where every square millimeter counts.
