An electronic component called a linear Hall effect sensor responds to magnetic fields by generating an electrical output proportional to the magnetic flux density.
In many different applications, including proximity sensors, liquid level sensors, and DC brushless motors, it may measure the strength, motion, or position of magnetic fields.
It provides linear output, temperature stability, and low energy consumption. The Hall effect is used to create a voltage difference, which is detected and amplified for processing or display.
A device that can gauge the direction and strength of a magnetic field and generate a proportional electrical output is known as a linear hall effect sensor. It is based on the Hall Effect, which happens when a conductor is exposed to a magnetic field and produces a voltage differential across it.
The following are some applications for linear hall effect sensors: Indicating whether a system is in one of two fixed mechanical positions, such as open or closed, a switch can detect the presence or absence of a magnet.
location measurement: A linear sensor can produce a signal that varies with distance or angle in response to the absolute location or angular movement of a magnet.
Speed and direction sensing: For uses like motor commutation or rotational encoding, a latch can measure the speed and direction of a revolving magnet and encode the information as a digital signal.
The Global Linear Hall Effect Sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The TMAG5231 is a low-power, low-voltage Hall-effect switch sensor that can determine if a magnetic field is there or absent and outputs a low voltage when the field is stronger than a predetermined threshold. It can detect both the north and south poles of a magnet thanks to its omnipolar response.
It has a push-pull output, thus no external pull-up resistor is required to drive both high and low voltages. It functions between a temperature range of -40°C and 125°C2 and a VCC range of 1.65 V to 5.5 V. It is offered in packages SOT-23 and X2SON.
The DRV5053 is a high-voltage, linear Hall-effect sensor that can determine the direction and strength of a magnetic field and provide an analogue output voltage that is proportionate to it, ranging from 0 to 2 volts.
It features a bipolar response, which enables it to detect both positive and negative magnetic fields. At no magnetic field, it produces a voltage that fluctuates between around 1 V.
It can drive a load with up to 2.3 mA sink and 300 A source currents thanks to its amplified output stage. It functions between a temperature range of -40°C and 125°C2 and a VCC range of 2.5 V to 38 V. It comes packaged in SOT-23 and TO-92 formats.
