Magnetic sensors, also known as switches, are devices that detect changes in an applied magnetic field and convert them into an electrical signal. The MLX90217LUA-CAA-000-SP is one such device. This device offers solid-state switching capabilities, which makes it an ideal choice for a wide range of applications.

The MLX90217LUA-CAA-000-SP is a highly sensitive, integrated and industrial-grade magnetic sensor that is capable of detecting magnetic fields from DC to 50 kHz. The device can operate in a range of temperatures from -10°C to +120°C, making it suitable for a wide range of applications that may be exposed to harsh environments.

The device is particularly well-suited for applications such as motor commutation, current sensing, level sensing, and position sensing. Additionally, the MLX90217LUA-CAA-000-SP is capable of handling very high currents in excess of 18 A while providing high immunity to EMI. The device is also protected from reverse-polarity and overvoltage conditions.

The MLX90217LUA-CAA-000-SP operates on the principle of Hall-effect magnetic sensing. When an external magnetic field is applied to the device, a Hall voltage is generated, which corresponds to the magnitude and polarity of the applied field. The Hall voltage is then amplified and compared to the two preset thresholds set in the device. If the Hall voltage is found to be equal or higher than the high threshold, the device’s output is switched to a high voltage. Conversely, if the Hall voltage is equal or lower than the low threshold, the device’s output is switched to a low voltage.

The MLX90217LUA-CAA-000-SP offers very high immunity to EMI, which makes it suitable for applications in environments with high levels of EMI. Additionally, the device includes a special feature called “smart shutdown” that reduces power consumption when there is no external magnetic field present. The device is also RoHS compliant and includes safety features such as overvoltage,...
