MLX92215LSE-ACA-000-RE

The MLX92215LSE-ACA-000-RE is a Hall effect sensor, belonging to the magnetic sensors – switches (solid state) category of sensors. Primarily, these sensors detect the presence or absence of a magnetic field, and are used in many consumer and industrial applications. There is a wide range of different types of Hall effect sensors, each with its own working principle and field of application, which is determined by its design and specification.

The MLX92215LSE-ACA-000-RE is a two-channel, bidirectional, single-ended Hall effect sensor IC which features a reliable, accurate detection capability. It is designed for applications such as motor speed and position sensing, current sensing, fault detection and protection, and power supply control, over a range of industries.

The MLX92215LSE-ACA-000-RE is a small and low profile package, with a height of 1 mm. It is suitable for use in automotive and space constrained systems. It provides a range of diagnostic features, such as over and under temperature sensing, overtemperature warning, Vdd and reference pin monitoring, and supply voltage and polarity protection.

The IC features an on-chip momentary magnetic field switch, with a Hall plate, magnet and embedded demagnetization coil for optimal usability. It also has a two-wire serial interface with a SPI-compatible, open-drain interface. Its bidirectional technology offers a wide dynamic range of magnetic fields, allowing detection of both positive and negative fields, and is capable of sensing up to 5.15 mT (milliTesla) of total magnetic field strength.

In terms of operation, the MLX92215LSE-ACA-000-RE works by detecting the presence of a magnetic field. When the included magnet is placed near the integrated Hall plate, an electrical response is generated that corresponds to the strength and direction of the magnetic field. This voltage is sensed, conditioned, and then fed into an output signal pin.

The output signal pin switches at a predefined threshold, allowing the IC to detect the presence of the magnetic field. This output signal is then used to control various components in motor control systems, such as relays, fans, speed sensors, and other systems.

MLX92215LSE-ACA-000-RE is suitable for a wide range of applications, as it has a high level of accuracy and sensitivity. In addition, it is simple to use as it is a two wire IC, and it has a variety of safety features including fault protection and temperature monitoring. It is also relatively inexpensive and able to meet the needs of a wide range of applications.

Overall, the MLX92215LSE-ACA-000-RE is an excellent Hall effect sensor for applications such as motor speed and position sensing, current sensing, fault detection and protection, and power supply control. Its wide magnetic field detection range, bi-directional capabilities, and on-chip magnet makes it an inexpensive and reliable solution.
