UGN3503 Hall Effect Sensor Overview

The UGN3503 is a Hall effect sensor with linear characteristics, designed to identify the presence of magnetic fields and generate a corresponding output voltage. It delivers an analog output signal that is directly related to the intensity of the magnetic field. This sensor is extensively employed in a variety of magnetic sensing applications.

Key Features

• Linear Output: The UGN3503 generates an analog voltage output that varies linearly with the strength of the magnetic field.
• High Sensitivity: The sensor exhibits high sensitivity, even in the presence of weak magnetic fields.
• Wide Operating Range: It is capable of functioning effectively in a broad temperature range, from -40°C to +85°C.
• Low Current Consumption: The sensor typically consumes around 9 mA of current.
• Easy Integration: Its compact size and minimal pin count facilitate easy incorporation into circuits.

Pin Configuration

• Vcc (Power): This is the supply voltage necessary for the sensor's operation, typically ranging from 4.5V to 6V.
• GND (Ground): This is the circuit's ground connection.
• Vout (Output): This is the analog output voltage, which fluctuates with the strength of the magnetic field.

Applications

• Automotive: Used in ABS brake systems and steering angle sensors.
• Industrial Control: Utilized for motor speed control and position sensing.
• Consumer Electronics: Employed for magnetic cover detection in mobile phones and tablets.
• Medical Devices: Used for magnetic field measurements and detections.

Operating Principle

The UGN3503 operates based on the Hall effect. The current flowing through the semiconductor material inside the sensor is deflected by a magnetic field, creating a voltage difference across the material's sides. This voltage difference, proportional to the magnetic field strength, is outputted as an analog voltage signal by the sensor.
The UGN3503 Hall sensor is a trusted solution for a wide range of applications that require accurate magnetic field measurements. Its user-friendly nature and superior performance make it a preferred choice for engineers and designers.
