Economic Linear Hall Sensor IC



SC4001 is a small, economical, linear Hall sensor chip whose output voltage varies proportionally to the supply voltage and to the intensity of the magnetic field it induces.
The SC4001’s zero output voltage (without magnetic field) defaults to half of the supply voltage, with a typical sensitivity of 1.4 mV/Gs.
The typical working voltage of the chip is 5.0V, the limit voltage can be up to 30V, the working temperature range supports -40–125℃, suitable for commercial, consumer and industrial fields.
These devices are available in a 3-pin SIP package (UA) and a 3-pinSOT-23 style package (SE). Both packages are lead (Pb) free, with 100% matte tin lead frame plating.


  • 2.5 to 5.5V wide supply voltage range
  • Single current sourcing output
  • Low noise output eliminates the need for filtering
  • -40℃ to 125℃ wide ambient temperature range
  • Responds to either positive or negative gauss
  • Resistant to mechanical stress
  • 3-pin SIP and SOT23 package is available
