A1147ELHLT is a magnetic sensor-switch integrated chip produced by Allegri, a highly-acclaimed USA chip maker. It is one of the most commonly used, most versatile and widely utilized chips in the industry. As a solid-state Sensor-Switch it can be employed in fields like sensor networks, medical and home automation as well as for appliance control and security applications.

A1147ELHLT comprises a highly sensitive Hall effect-based (electromagnetic) switch and is capable of detecting a magnetic field using several specialized magnets, placed in such a way as to detect variations in the magnetic field surrounding the device. This device is usually installed in metal surfaces and is employed in fields requiring input from the magnetic field, like magnetometers, magnetic relays and control switches, where the A1147ELHLT was specifically designed for.

In order to power up the A1147ELHLT, a steady current needs to be supplied to the device, usually within the range of 2.7V to 5V DC. The output of the device (voltage levels) is highly dependent on the strength of the magnetic field the device is exposed to. This is also the conventional limitation of Hall-effect-based devices, where the maximum output capability is determined by the strength of the magnetic field surrounding the device.

Furthermore, A1147ELHLT comes with several features which set it apart from other Hall-effect sensors. It has a bipolar output waveform and offers an isolated output which can be used in many applications, providing greater flexibility than non-isolated alternatives. When exposed to a large magnetic field, it will switch to a higher output state. Furthermore, it can detect several magnets in close proximity. This opens up application areas which require several magnets in closely-spaced proximity for device control and security purposes.

A1147ELHLT can also be equipped with an output circuitry which allows for the necessary voltage and/or current output interface for regulating the device output. The output from this device generally consists in logic-level levels, such as 0-5V for digital signals or an increasing/decreasing voltage for analog signals. Depending on the application, the voltage and current output can be configured to meet the application requirements.

The typical operating range of A1147ELHLT is within the range of 300 G to 500 G, that is 300 times the Earth’s magnetic field (as measured at sea level). As a result, it is ideal for proximity switches and detectors, as well as for measuring the strength of a magnetic field in a specific point in space. The magnetic switching point of the chip usually lies within the range of 10 G to 70 G, and can be adjusted by using an external resistor.

In summary, A1147ELHLT is a multifunctional Hall-effect-based integrated chip which provides many advantages for applications requiring the detection of a magnetic field and the output of logic-level as well as analog signals. It offers an isolated output, as well as optimized voltage and current characteristics, making it applicable in a variety of scenarios. Moreover, it is considered to be amongst the most reliable and durable chip available on the market, enabling a long service life and reliable operation in challenging applications.
