Instructions:

1. Power Supply:

   • Connect the input voltage (V_IN) between 1.7V and 5.5V to the VCC pin.
   • Ensure the ground (GND) pin is connected to the system ground.

2. Output Configuration:

   • The output (OUT) is open-drain and requires a pull-up resistor to a suitable voltage level.
   • The pull-up resistor should be chosen based on the desired output current and the pull-up voltage.

3. Reset Functionality:

   • The device will assert the reset signal (OUT) when the input voltage drops below the reset threshold (V_RST).
   • The hysteresis voltage (V_HYS) ensures stable operation by preventing oscillation around the threshold.

4. Temperature Considerations:

   • Operate the device within the specified operating temperature range (-40°C to 125°C) to ensure reliable performance.
   • Store the device within the storage temperature range (-65°C to 150°C).

5. Handling:

   • Handle the device with care to avoid damage from electrostatic discharge (ESD).
   • Follow proper soldering techniques to avoid thermal stress during assembly.

6. Testing:

   • Test the device under typical operating conditions to verify correct functionality.
   • Use a multimeter or oscilloscope to monitor the output signal and input voltage levels.
