Instructions for Using A3967SLBT

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 4.5V to 55V.
   • Connect the Vcc pin to a stable power source.

2. Standby Mode:

   • The device consumes approximately 10 μA in standby mode.
   • Use the SLP pin to control the standby mode.

3. Temperature Considerations:

   • The operating temperature range is from -40°C to 125°C.
   • The storage temperature range is from -40°C to 150°C.
   • Monitor the thermal shutdown temperature (Tsd) of 160°C to prevent damage.

4. Output Current:

   • The maximum output current per phase is 700 mA.
   • Ensure the load does not exceed this limit to avoid overcurrent protection (OCP).

5. Under-Voltage Lockout (UVLO):

   • The device will shut down if the supply voltage drops below 2.8V and restart when it rises above 3.1V.

6. Step Control:

   • The step angle is 1.8° for full-step operation and 0.9° for half-step operation.
   • Use the STEP and DIR pins to control the stepping direction and timing.

7. Protection Features:

   • The device includes over-current protection (OCP) which triggers at approximately 1.5A.
   • Ensure proper heat dissipation to prevent thermal shutdown.

8. Pin Configuration:

   • Refer to the datasheet for the specific pin configuration and connections.

9. Application Notes:

   • For optimal performance, use a heatsink or other cooling methods if operating at high currents or temperatures.
   • Follow the recommended PCB layout guidelines to minimize electromagnetic interference (EMI).
