Magnetic Sensors - Switches (Solid State): MLX92221LSE-AAA-003-RE Application Field and Working PrincipleThe MLX92221LSE-AAA-003-RE is a solid state switch manufactured by Melexis. It is designed for use as a Hall-effect, contactless solution for enabling or disabling electrical circuits. This device is a part of a family of reliable, low power, high temperature, Hall-effect-based switches and is suitable for applications in the automotive, industrial, and medical fields.The MLX92221LSE-AAA-003-RE is designed to detect changes in the magnetic field around it. The device is made up of an integrated circuit fabricated on a silicon wafer that houses a transistor, Hall-effect transducer, and a few other components. The transducer is sensitive to the presence of a magnetic field, creating a signal that triggers the switch to open or close.When a magnetic field is present, the Hall-effect transducer senses the magnetic field and produces a positive or negative charge, depending on the polarity of the field and the orientation of the device. The device then sends a signal to the transistor, which will either turn on or off, depending on the strength and orientation of the field.In its applications, the MLX92221LSE-AAA-003-RE provides reliable, low-power switching solutions, and operates within a wide temperature range. The device also offers user-programmable hysteresis, current consumption, pulse width and delay, and open collector voltage options.One of the key advantages of the MLX92221LSE-AAA-003-RE is its reliability and long-term stability. The device is designed with a robust design that eliminates mechanical failures and includes protective measures such as protection against over-voltage, vibration, voltage spikes, and reverse bias current. The device is designed for use in high-temperature environments and can handle a range of temperatures from -40°C to +150°C.The MLX92221LSE-AAA-003-RE is commonly used in automotive applications such as automotive door locks and remote control door release systems. It is also widely used in medical devices, industrial applications, and as a safety device for protecting sensitive machinery.In summary, the MLX92221LSE-AAA-003-RE is a reliable, low-power Hall effect-based switch and is suitable for a variety of applications in automotive, medical, and industrial settings. Its robust design ensures a long-term stability in a wide temperature range and its user-programmable features provide greater flexibility for applications.
