Design Notes
Place a 0.1uF ceramic capacitor close to the VCC pin and a 10uF electrolytic capacitor near the motor supply to handle current transients. The VREG pin requires a 1uF capacitor for stability. Ensure the exposed thermal pad is soldered to a large copper area for heat dissipation.
At 1A output and 6.8V supply, power dissipation can be significant. The HVSSOP package has a thermal resistance of approximately 40C/W. For continuous operation at high currents, provide adequate PCB copper and consider airflow. The device has thermal shutdown protection, but it should not be relied upon for normal operation.
Do not exceed the absolute maximum supply voltage of 7V. Ensure the motor's back-EMF does not exceed the supply voltage, as this can damage the device. Use flyback diodes across the motor if it is inductive. The ISENSE pin should be connected to a low-value sense resistor for current limiting; if not used, connect to GND.
Compliance Information
RoHS compliant and halogen-free (no Sb/Br) per TI product page. Not AEC-Q100 qualified; use DRV8832QDGQRQ1 for automotive.
