The Texas Instruments TMP390-Q1 is an ultra-low power, dual-channel temperature switch designed for automotive applications. It offers independent overtemperature (hot) and undertemperature (cold) detection, with trip temperatures and hysteresis programmed by external resistors.
Key electrical specifications include a wide supply voltage range of 1.62V to 5.5V and ultra-low power consumption of 0.5 µA typical. The device provides accuracy of ±1.5°C from 0°C to +70°C and ±3.0°C from -55°C to +130°C. Channel A is for overtemperature detection, ranging from +30°C to +124°C in 2°C steps, while Channel B is for undertemperature detection, ranging from -50°C to +25°C in 5°C steps. Hysteresis options of 5°C, 10°C, and 20°C are available.
This temperature switch is AEC-Q100 qualified and functional safety-capable, making it suitable for automotive infotainment systems, cameras, and radar/lidar applications. It features open-drain outputs and a trip test function for in-system testing. The TMP390AQDRLTQ1 is available in a compact SOT-563 (1.60-mm x 1.20-mm) 6-pin package, designed for surface mounting.
