The MLX90217LUA-CCA-000-BU is an intelligent, integrated magnetic switch and hall-effect, precise closed-loop position sensor which is categorized as a Magnetic Sensor - Switch (Solid State). It has been designed to provide fast response and accurate positioning for current, open or short circuit detection within a highly compact form factor.In terms of its application field, the MLX90217LUA-CCA-000-BU is particularly suitable for applications such as in automotive, household goods and even consumer electronics. In automotive applications, it can be used to detect changes in the steering angle or throttle position and ensure the safety of onboard systems by monitoring the system’s operation. In addition, it can be used to increase the performance of engine control systems and reduce fuel consumption by monitoring parameters such as air/fuel ratio and intake manifold absolute pressure. In consumer electronics and household goods applications, it can be used to detect the amount of movement or rotation of switches, levers or even objects and thereby detect the state of the system.As for its working principle, the MLX90217LUA-CCA-000-BU is a two-wire device that combines a closed-loop Hall-effect sensor which functions according to a Hall Effect sensing principle with a built-in analog output amplifier and temperature compensation for accurate and precise measurements over its operating temperature range [-40ºC to +125ºC (T A)]. The sensor also has an internal non-volatile memory which can store the calibration settings to ensure accuracy and a signal conditioning circuit which can provide amplified and filtered output signals.The Hall-effect sensing element is based upon a patented thick-film technology which consists of a C-type magnet, with a special compact Hall-effect sensor integrated within it. This C-type magnet is mounted on an integrated positioning system which allows it to move along a pre-defined path. The position of the magnet is determined by the position of this positioning system in relation to a stationary independent power theta board. When the position of the magnet changes by a particular amount, the Hall-effect element is triggered and creates a magnetic field, which is then measured by the Hall-effect sensor.The output of this sensor then undergoes signal conditioning which includes amplification and filtering before it is sent to an analog output amplifier which in turn provides a precise analog output signal. This output signal is then used to control various systems such as an engine control unit (ECU). The accuracy and precision of the MLX90217LUA-CCA-000-BU over its operating temperature range is also ensured through the use of a temperature compensation circuit which is integrated in the internal circuit of the device.In conclusion, the MLX90217LUA-CCA-000-BU is a Magnetic Sensor - Switch (Solid State) which is designed to provide fast response and accurate positioning for current, open or short circuit detection within a highly compact form factor. It has been designed to be used in multiple applications such as automotive, consumer electronics and even household goods. The working principle of this device is based upon a closed-loop Hall-effect sensor which is integrated with a patented thick-film technology and is combined with an analog output amplifier and temperature compensation circuit which ensures accuracy and precision over its operating temperature range.
