General Description:

The AH3503 is an analog signal output Hall IC with output voltage changes corresponding to magnetic field changes. It includes built-in circuits such as reverse voltage protector, voltage regulator, and temperature compensation circuit, ensuring stable operation across temperature ranges. It is available in SOT-23-3L and TO-92UA packages, both lead-free with matte tin plating.

Electrical Operating Characteristics:
  • Supply Voltage (VCC): 3.5 to 6.5 V
  • Null Voltage: 2.3 V
  • Output Voltage: 0.1 to 4.9 V
  • Supply Current: 2.7 to 7 mA
Magnetic Operating Characteristics:
  • Sensitivity: 12 to 17 mV/mT
  • Operating Temperature: -40 to 125ºC
  • Storage Temperature: -50 to 160ºC
Magnetic Behavior:

The sensor operates through linear, nonlinear, and saturation areas during magnetic induction changes. At zero magnetic field, the output voltage is half of Vcc. The output voltage decreases or increases with the magnetic field until saturation is reached.
