Instructions:

1. Power Supply:

   • Connect the Vcc pin to a power supply within the operating voltage range (4.5V to 5.5V).
   • Connect the GND pin to the ground of the power supply.

2. Output Connection:

   • The output is an open collector, so connect a pull-up resistor between the output pin (OUT) and Vcc.
   • The typical value for the pull-up resistor is 4.7k惟 to 10k惟.

3. Magnetic Field Detection:

   • Place a magnetic field near the sensor to trigger the output.
   • The sensor will switch the output to low (0V) when the magnetic field strength exceeds the sensitivity threshold (100 Gauss).

4. Handling Precautions:

   • Avoid exposing the sensor to temperatures outside the operating and storage temperature ranges.
   • Handle the component with care to avoid static damage.

5. PCB Layout:

   • Ensure proper clearance around the component to facilitate heat dissipation.
   • Follow standard PCB design practices for surface mount components.

6. Testing:

   • After mounting, test the sensor by applying a known magnetic field and verifying the output response.
   • Use a multimeter to check the output voltage levels (high and low states).
