The maximum ratings may not be exceeded under any circumstances. Operating the circuit at or near more than one maximum rating at a time for extended periods shall be avoided by application design.

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.

Table 28.1 Thermal characteristics TQFP48-EP

The thermal resistance in an actual layout can be tested by checking for the heat up caused by the standby power consumption of the chip. When no motor is attached, all power seen on the power supply is dissipated within the chip.

Figure 3.1 Standard application circuit

The standard application circuit uses a minimum set of additional components. Eight MOSFETs are selected for the desired current, voltage and package type. Two sense resistors set the motor coil current. See chapter 9 to choose the right value for sense resistors. Use low ESR capacitors for filtering the power supply. A minimum capacity of 100μF per ampere of coil current near to the power bridge is recommended for best performance. The capacitors need to cope with the current ripple caused by chopper operation. 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. In order to minimize linear voltage regulator power dissipation of the internal 5V and 11.5V voltage regulators in applications where VM is high, a different (lower) supply voltage should be used for VSA (see chapter 3.2).
