the FAULTB pin, it can be left unconnected. But if the
FAULTB pin has to be monitored, it should be pulled high
externally through R
through R
controller if the AOZ1401DI fails. Choose the resistors
with high values, and values between 22kΩ and 100kΩ
should be sufficient.

PCB Layout Guidelines
AOZ1401DI uses DFN 2x2 package with a thermal PAD.
The thermal PAD should be thermally coupled with the
PCB ground plane for good thermal performance, This
will require a copper pad directly under the IC in most
applications. This copper pad should be connected to the
ground plane with an array of thermal vias. C
R
ILIM
and R
BAT
should be located close to the IC.
