AD620-02E Magnetic Sensors - Switches (Solid State)

AD620-02E from Allegro MicroSystems is a linear Hall effect magnetic sensor switch (solid state) designed for use in a wide range of applications. The linear Hall effect magnetic sensor switch is a device that responds to a magnetic field by switching to a digital output signal when the input signal is greater than a particular threshold. The AD620-02E can be used to detect when a certain magnet is activated and can be used to trigger events or alarms based on the input to the device.The AD620-02E is specified for use in a wide range of applications, including automotive operations, security systems, alarms, and household appliances. The 50 mA open collector output makes it ideal for applications where a high-current and low-voltage signal is required. This device is capable of providing accurate digital output signals for a wide range of magnetic fields from as low as 200 mT to as high as 5.25 kT.The main components of the AD620-02E magnetic sensor switch are a Hall element, a signal conditioning circuit, an integrated amplifier, a low power CMOS latch and an output driver. The Hall element is a magneto-sensitive device that produces an output voltage proportional to the strength of the external magnetic field. The signal conditioning circuit detects changes in the input signal to the Hall element and controls the current to the amplifier. The amplifier then amplifies the Hall output signal to the proper level and the low-power CMOS latch is used to either enable or disable the output driver depending on the strength of the input signal.The AD620-02E has a standard magnetic field response of 1.2 mT to 5.25 kT and a repeatability of < 0.3%. This repeatability ensures that the device is accurate and reliable in its output signals. It also has a fast response time of < 2 ms and a low power consumption of < 6 mA. This makes it a great choice for applications that require a fast response to a changing magnetic field.The AD620-02E is highly configurable with various programming options, such as thresholds, hysteresis, inversion, pause time and outputs. It is also available in several package varieties, including through hole, surface mount, and micro leadless packages. This makes it possible to customize the device for specific customer requirements. The device is also capable of operating in a wide range of temperatures, from -40°C to +125°C.In summary, the AD620-02E is an efficient and reliable solution for detecting the presence or absence of a magnetic field in a wide range of applications. Its features such as fast response time, low power consumption, and high configurability make it a great choice for applications that require a reliable and accurate device for detecting changes in a magnetic field.
