One of the most influential components on the thermal performance of a package is board design. In order to take full advantage of the heat
dissipating abilities of the PowerPAD packages, a board must be used that acts similar to a heat sink and allows for the use of the exposed (and
solderable), deep downset pad. See Appendix A of the
PowerPAD Thermally Enhanced Package
application note, TI literature number
SLMA002.
For both DAD and DAP packages.

Connect LDROUTA to PVDDA2 and connect LDROUTB to PVDDB2. Under this condition, the H-bridge forward on-state resistance is increased.
This increases internal power dissipation. Maximum output power may need to be reduced to meet thermal conditions.
