Instructions for Using A3959SB

1. Power Supply:

   • Ensure the supply voltage (VCC) is within the range of 8.0V to 40.0V.
   • The logic input voltage (VLOGIC) should be between 2.7V and 5.5V.

2. Temperature Management:

   • The operating temperature (TOPR) should not exceed 150°C.
   • Store the device within the storage temperature range (-65°C to 150°C).

3. Current Handling:

   • The maximum current per phase (IOUT) is 1.5A, with a typical value of 1.0A.
   • Ensure the load does not exceed this limit to avoid damage.

4. Microstepping:

   • The device supports up to 1/16 microstep resolution for smoother motor operation.

5. Step Accuracy:

   • The step angle error is typically ±5% of a full step.

6. Thermal Protection:

   • The device will shut down if the internal temperature reaches 160°C to prevent thermal damage.

7. Under-Voltage Lockout:

   • The device will enter an under-voltage lockout state if the supply voltage drops below 6.5V.

8. Installation and Handling:

   • Use appropriate heat sinks or cooling solutions to manage heat dissipation.
   • Handle the device with care to avoid static discharge and physical damage.

9. Testing and Validation:

   • Before deploying the device in a final application, test it thoroughly to ensure it meets all performance specifications.

10. Compliance and Standards:

    • Ensure that the device complies with relevant safety and regulatory standards for your specific application.
