The linear sensor is an analog signal output Hall IC, and the output voltage changes with the magnetic flux density. It has built-in circuit units such as reverse voltage protector, voltage regulator, temperature compensation circuit, Hall voltage generator, signal amplifier, etc. The high performance voltage regulator and temperature compensation circuit ensure that the sensor operates steadily over the operating temperatures range, and the reverse voltage protection circuit prevents the sensor from being damaged by the reverse voltage.
Produced with bipolar technology, a linear Hall IC is available in two package types: SOT-23-3L (Type M) and TO-92UA (Type UA). Each package is lead (Pb) free, with 100% matte tin plated leadframes.
Vo raises with increasing B (N pole)
The sensor will pass linear area /nonlinear area/ saturation area during the magnetic induction increases. When there is no magnetic field that applies in sensor (B=0), the output voltage of sensor is only half of Vcc (Vcc/2); when S pole faces mark surface of the sensor and is close to it gradually (B→-∞), the output voltage begins to decrease, and the voltage doesn't reduce with the increased magnetic field after it reaches saturation voltage; When the N pole of magnet faces the mark surface of the sensor and is closed to it gradually (B→+∞), the output voltage of sensor begins to increase, and it doesn’t increase with the increased magnetic field after it reaches saturation voltage.
Note: the TO92UA package is the opposite.
