The Texas Instruments TMP390AQDRLRQ1 is an ultra-small, dual-channel temperature switch designed for automotive applications. It offers independent overtemperature and undertemperature detection with resistor-programmable trip points and hysteresis options. The device operates over an extended temperature range of -55°C to +130°C and features an accuracy of ±3.0°C across this range.
With ultra-low power consumption of 0.5 µA typical, the TMP390AQDRLRQ1 is suitable for power-sensitive designs. It supports a supply voltage range of 1.62 V to 5.5 V and provides open-drain outputs. The trip temperatures and hysteresis are programmed using external resistors, allowing for flexibility in design. Channel A is for overtemperature detection, with trip points from +30°C to +124°C in 2°C steps. Channel B is for undertemperature detection, with trip points from -50°C to +25°C in 5°C steps. Hysteresis options include 5°C, 10°C, and 20°C.
This temperature switch is AEC-Q100 qualified and functional safety-capable, making it ideal for automotive infotainment systems, cameras, and radar/lidar applications. It is available in a compact SOT-563 (1.60-mm × 1.20-mm) 6-pin package, suitable for surface mounting.
