SmartSwitch
General Description
The AAT4608 SmartSwitch is a member of
AnalogicTech's
Application
MOSFET (ASPM) product family. It is a Current
Limited P-channel MOSFET power switch designed
for high-side load-switching applications. This switch
operates with inputs ranging from 2.7V to 5.5V, mak-
ing it ideal for both 3V and 5V systems. An inte-
grated current-limiting circuit protects the input sup-
ply against large currents which may cause the sup-
ply to fall out of regulation. The AAT4608 is also pro-
tected from thermal overload which limits power dis-
sipation and junction temperatures. It can be used
to control loads that require up to 1 A. Current limit
threshold is programmed with a resistor from SET to
ground. The quiescent supply current is typically a
low 15μA max.
Specific
Power
The AAT4608 is available in a 5 pin SOT-23 spec-
ified over -40 to 85°C.
