Linear Hall Effect Integrated Circuit Hall Element SS49E
The SS49E is a Linear Hall Effect Integrated Circuit (IC) that senses magnetic fields and outputs a linear voltage proportional to the magnetic field strength. It is commonly used in various applications, including linear position sensing, linear current sensing, and in rotary position sensors. It has a small outline IC package and operates over a specified temperature range and voltage range, typically consuming low supply current. The output is typically an open-collector linear voltage, with a magnetic sensitivity of around 2mV/G.
Description
The SS49E is a linear Hall effect integrated circuit (IC), also known as a Hall element, that is used to measure magnetic fields. It is a small, low-power device that outputs a voltage proportional to the strength of the magnetic field it is exposed to. This makes it useful for a variety of applications, such as in position and speed sensing, current sensing, and in measuring the strength of magnetic fields.
The SS49E typically operates on a supply voltage of 2.5 to 5.5V and consumes very little power, making it well suited for battery-powered or portable applications. The output voltage is proportional to the magnetic field strength and can be used to determine the position or orientation of a magnetic target. The linear output makes it suitable for use in linear applications, where the output voltage is proportional to the magnetic field strength.
The specifications for the SS49E include:
- Operating voltage range: 2.5 to 5.5V
- Output voltage range: Vcc/2 to Vcc-1V (linear output)
