The UGN3113U is a unipolar Hall-effect switch manufactured by Allegro MicroSystems, LLC. Hall-effect switches are semiconductor devices that detect the presence of a magnetic field. When a magnetic field of sufficient strength is applied, the switch turns on or off, providing a digital output signal. Unipolar Hall-effect switches respond to a magnetic field of a single polarity (either north or south).

Applications

• Brushless DC (BLDC) Motor Control: Used for rotor position sensing in BLDC motors, enabling precise control of motor speed and direction.
• Proximity Sensing: Employed in proximity sensors for detecting the presence of objects or components.
• Position Sensing: Utilized in position sensors for determining the position of a moving part or component.
• Flow Measurement: Integrated into flow meters for detecting the rotation of a turbine or impeller.
• Level Detection: Used in level sensors for detecting the level of a liquid or solid in a container.

Features

• Unipolar Hall-Effect Switch: Responds to a magnetic field of a single polarity.
• Digital Output: Provides a digital output signal that switches on or off in response to the magnetic field.
• High Sensitivity: Offers high sensitivity to magnetic fields, allowing for reliable detection of weak magnetic fields.
• Wide Operating Voltage Range: Operates over a wide voltage range, making it compatible with various electronic systems.
• Small Package: Available in a small package for space-constrained applications.

Benefits

• Accurate Sensing: Provides accurate and reliable detection of magnetic fields.
• Non-Contact Sensing: Operates without physical contact, eliminating wear and tear.
• Long Life: Offers a long operating life due to the absence of mechanical parts.
• Low Power Consumption: Consumes very little power, making it suitable for battery-powered applications.
• Robust Performance: Resistant to shock, vibration, and temperature variations.
