PCB Layout Issues

For optimum voltage regulation, place the battery pack

as close as possible to the device’s VBAT and VSS pins

to minimize voltage drops along the high-current-

carrying PCB traces.

If the PCB layout is used as a heat sink, adding multiple

vias in the heat sink pad can help conduct more heat to

the backplane of the PCB, thus reducing the maximum

junction

temperature.

Figure 6-3,

Figure 6-4

and

Figure 6-5 depict a typical layout with PCB heatsinking.
