Thermal Information
The following table shall give an idea on the thermal resistance of the package. The thermal resistance for a four layer board will provide a good idea on a typical application. Actual thermal characteristics will depend on the PCB layout, PCB type and PCB size. The thermal resistance will benefit from thicker CU (inner) layers for spreading heat horizontally within the PCB. Also, air flow will reduce thermal resistance.
A thermal resistance of 30K/W for a typical board means, that the package is capable of continuously dissipating 3.3W at an ambient temperature of 25°C with the die temperature staying below 125°C. Note, that a thermally optimized layout is required.

Typical Application
Figure 3.1 Standard application circuit
The standard application circuit uses a minimum set of additional components. Two sense resistors set the motor coil current. See chapter 8 to choose the right sense resistors. Use low ESR capacitors for filtering the power supply. The capacitors need to cope with the current ripple cause by chopper operation. A minimum capacity of 100μF near the driver is recommended for best performance. Current ripple in the supply capacitors also depends on the power supply internal resistance and cable length. VCC_IO can be supplied from 5VOUT, or from an external source, e.g. a 3.3V regulator.
