General Description

The AH3519 is an analog signal output Hall IC with output voltage changing according to the magnetic field. It includes built-in circuits like reverse voltage protector, voltage regulator, and temperature compensation circuit. It is produced with bipolar technology and available in SOT-23-3L and TO-92UA packages.

Electrical Operating Characteristics
  • Supply Voltage: 3.5 to 10.5 V
  • Output Voltage: 0.1 to 4.9 V
  • Supply Current: 5.5 to 8 mA
Magnetic Operating Characteristics
  • Magnetic Flux Density: Unlimited
  • Operating Temperature: -40 to 125ºC
  • Storage Temperature: -50 to 160ºC
Magnetic Behavior

The sensor's output voltage changes with the magnetic field, passing through linear, nonlinear, and saturation areas. The output voltage is half of Vcc when no magnetic field is applied.

Linear Hall Sensor 9 Magnetic Behavior Vo raises with increasing B (S 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 N 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 S pole of magnet faces the mark surface of the sensor and is closed...
