On a quick glance, the IC datasheet looks OK. It's an actual motor driver IC, meaning it can provide you with a proper current (torque) limiting, although slightly inaccurate.
The fact it has internal MOSFETs simplifies the layout work a lot. Still, be careful with DC link bypass capacitors - minimize distance to the IC power pins and ground plane, use a combination of MLCCs (say something like a bunch of 0.47uF 50V in 0805) and traditional crappy and lossy aluminum electrolytic capacitors (for ESR, damping).
Thin traces usually aren't a problem in tight integration - make them short. Standard 1oz copper has resistance of 0.5 mOhm per square (Google for this if you don't know the concept and the unit sounds weird - Dave has a video about it). This means, even if you had a tiny trace with 0.3mm width, if it's also 0.3mm long, the resistance is 0.5 mOhm! Or if it's 0.3mm x 0.6mm, it's 1mOhm. This means, minimize the distance between parts, and your wiring loss problem disappears.
