Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the range of 2.7V to 5.5V.
   • Connect the Vcc pin to the positive supply and GND to the ground.

2. Output Configuration:

   • The output is an open collector type, which requires an external pull-up resistor.
   • Connect the pull-up resistor between the output pin and the supply voltage (Vcc).

3. Magnetic Field Application:

   • Apply a magnetic field of at least 15 mT to activate the sensor.
   • The sensor will release when the magnetic field drops below 5 mT.

4. Temperature Considerations:

   • Operate the device within the temperature range of -40°C to 85°C.
   • Store the device within the temperature range of -40°C to 125°C.

5. Response and Release Times:

   • The typical response time is 20 ms.
   • The typical release time is 10 ms.

6. Current Limitation:

   • Do not exceed the maximum output current of 20 mA to avoid damage to the device.

7. Handling and Storage:

   • Handle the device with care to avoid static discharge.
   • Store the device in a dry environment to prevent moisture damage.

8. Mounting:

   • Ensure proper mounting to avoid mechanical stress on the device.
   • Follow the recommended PCB layout guidelines for optimal performance.
