The LM50-Q1 (Grade-1) and LM50HV-Q1 (Grade-0) devices are AEC-Q100 automotive-grade analog temperature sensor that can measure temperature up to 125°C and 150°C, respectively, using a single positive supply. Unlike NTC thermistors, LM50-Q1 and LM50HV-Q1 do not require any external calibration, trimming or software linearization leading to simplifying the circuitry requirements. The output voltage of the devices are linearly proportional to temperature (10mV/°C) and has a DC offset of 500mV at 0°C. The offset allows reading negative temperatures without the need for a negative supply. The output voltage of these devices ranges from 100mV (at -40°C) to 1.75V (at 125°C) and 2V (at 150°C only for LM50HV-Q1), simplifying automotive ADC interfacing (including ADC integrated in MCU).
LM50HV-Q1 is designed for LDO-less application due to stable functionality across wide supply range of 3V to 36V. Trimming and calibration of LM50-Q1 and LM50HV-Q1 at the wafer level provide low cost and consistent accuracy: LM50-Q1 (±4°C across –40°C to 125°C) and LM50HV-Q1 (±3°C across –20°C to 125°C, ±3.5°C across –40°C to 150°C). Functional safety documentation is also available.
