LMT86QDCKRQ1is an AEC-Q100 Grade 0 qualified automotive analog output temperature sensor from Texas Instruments, supplied in a 5-pin ultra-small SC-70 surface-mount tape-and-reel package with 3000 units per reel. Delivering a linear analog voltage inversely proportional to ambient temperature with an average gain of -10.9 mV/°C, it operates across an extremely wide -50°C to +150°C sensing range, supports a 2.2 V to 5.5 V supply voltage, and achieves ±0.4°C typical accuracy with ±2.7°C maximum error over the full temperature span without user calibration. Featuring only 5.4 µA typical quiescent current, class-AB push-pull output with ±50 µA drive capability, short-circuit protection and functional safety supporting documentation, this precision CMOS sensor provides a cost-effective thermistor replacement for high-temperature automotive and industrial environments where reliable, space-saving temperature monitoring is required.
● Wide 2.2 V to 5.5 V supply voltage range natively supports 3.3 V and 5 V system rails, enabling direct connection to standard MCU and sensor power domains without additional regulation circuits.
● Ultra-low 5.4 µA typical quiescent current and 0.7 ms fast power-on time enable duty-cycled measurement architectures, minimizing standby power drain for battery-powered automotive wake-up and always-on monitoring systems.
● Linear -10.9 mV/°C analog output with push-pull class-AB stage drives capacitive and resistive loads directly, eliminating external buffer amplifiers and simplifying connection to on-chip ADC channels of microcontrollers.
● Industry-standard SC-70-5 pinout offers footprint compatibility with popular LM20 and LM35 temperature sensors, allowing drop-in replacement in existing designs with minimal PCB layout changes.
● Built-in output short-circuit protection, 2 kV HBM ESD rating and MSL Level 1 moisture sensitivity enhance field robustness and simplify inventory handling without dry-pack bake requirements.
