General Description
The AAT4681 SmartSwitch enables separate stand-alone
AC adapter and PMU USB chargers to independently con-
trol a single low R
and system power output. A 20V version is available for
multi-cell Li-ion applications and a 6V version is available
for single-cell Li-ion applications.
The two P-channel power MOSFETs required in UMPC
applications for controlling independent charger ICs can
be consolidated to a single device, saving space and
reducing cost. The single 20mΩ P-channel device in the
AAT4681/-1 has four times lower R
lent path resistance formed by two series devices.
Ordering options are available for multi-cell and single-
cell Li-ion versions. For the single-cell application, a 6V
device with dual independent gate control is available.
For 2-cell and 3-cell applications a 20V ordinary P-channel
device is available in the same package and pin configu-
ration. Both devices are available in the TDFN-10L 3mm
x 3mm package.
