The HAL516 SF-K magnetic sensors belong to the family of linear, compass integrated circuits (ICs). These miniature, high resolution sensors offer a solution for various detection applications, such as current, voltage, position, and velocity, as well as motion sensing. They are designed for use in a wide range of commercial and industrial products, including medical devices, consumer electronics, military equipment, automotive applications, aerospace, and robotics.The IC consists of a hysteric data converter, a special low offset current sampler, and two hall elements with a single integrated semiconductor chip. It includes adjustable gain and offset and uses a single, low voltage (3.3V) power supply. The hall elements in the IC measure the magnetic field in X and Y directions and provide a differential output signal proportional to the strength of the field in both directions. The output signals are then processed by the data converter and the output is provided as a fully digital signal that is proportional to the magnitude and direction of the external magnetic field.The HAL516 SF-K has two parts, the sensor core and the electronics, which supply the current to the sensor core. The sensor core consists of two hall elements arranged in pairs, each with an integrated transistor and a special low offset current sampler. The current sampler reads the data from the hall elements, and the data is then processed by the on-chip microprocessor and the output is provided in the form of a digital signal, which is proportional to the magnitude and direction of the magnetic field. The second part of the sensor is the electronics section, which is in charge of supplying the current to the sensor core.The major advantage of the HAL516 SF-K is its high sensitivity, and its ability to be used in a wide range of environments, which makes it a suitable choice for many applications. It has a wide dynamic range and a low noise level, and its high resolution makes it very precise. Additionally, the IC has an adjustable gain and offset, which allows it to detect small changes in the magnetic fields.In summary, the HAL516 SF-K magnetic sensor is a robust and efficient IC that offers a reliable solution for various detection applications. Its high sensitivity, wide dynamic range, low noise level, and adjustable gain and offset make it an ideal choice for many different applications, such as medical devices, consumer electronics, military equipment, automotive applications, aerospace, and robotics.
