Design Notes

The L6480H can dissipate significant power at high currents. For example, at 10A peak and 24V supply, power dissipation can exceed 5W. The HTSSOP-28 package has an exposed thermal pad that must be soldered to a copper area with thermal vias connected to a ground plane. Ensure adequate PCB copper area (at least 2 square inches) for heat spreading. Consider forced air cooling if ambient temperature exceeds 50C.

Place 100nF ceramic capacitors close to each VM pin and a 10uF electrolytic capacitor near the VM supply. For the logic supply, use a 100nF capacitor close to the VCC pin. Route the STEP and DIR signals away from high-current motor traces to avoid noise coupling. Use a ground plane to minimize EMI and provide a low-impedance return path.

Do not exceed the absolute maximum supply voltage of 85V. Ensure the motor supply is properly decoupled to prevent voltage spikes during switching. The SPI interface must be initialized correctly before enabling the outputs; otherwise, the device may not respond. Also, verify that the logic supply voltage is within 3.3V to 5V to avoid damage to the control logic.
