The VCC pin requires a local decoupling capacitor that is connected to GND. This capacitor ensures stability of the internal regulator from the VIN pin. The decoupling capacitor also provides the current pulses to drive the gates of the external MOSFETs through the driver output (OUTA and OUTB) pins. Place the decoupling capacitor close to the VCC and PGND pins, and track it directly to those pins.

The two ground pins (PGND and AGND) must be connected together with a short direct PCB connection.
