PCB Layout Consideration

The APL3200 is packaged in a thermally enhanced QFN

package. The package includes a thermal pad to provide

an effective thermal contact between the device and the

printed circuit board. Connecting the exposed pad to a

large copper ground plane on the backside of the circuit

board through several thermal vias for heatsinking is

recommended. Connecting the battery to BATT as close

to the device as possible provides accurate battery volt-

age sensing. All decoupling capacitors and filter capaci-

tors should be placed as close as possible to the device.

The high-current charge paths into DC, DCLV, USB, and

from the BATT pins must short and wide to minimize volt-

age drops.
