ADVANCE INFORMATION
Refer to the PDF data sheet for device specific package drawings
To achieve optimal thermal performance, connect the exposed thermal pad (connected to VBB pin) to a large broken copper pour. On the top PCB layer, the pour can extend beyond the package dimensions as shown in the example below. In addition to this, TI recommends to also have a VBB plane either on one of the internal PCB layers or on the bottom layer.
Vias must connect this plane to the top VBB pour. TI recommends that the IO pins that connect to the controller be routed through a via and internal or bottom PCB layer.
