SmartSwitch
General Description
The AAT4611 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 AAT4611 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. In shutdown mode, the supply cur-
rent decreases to less than 1μA.
Specific
Power
The AAT4611 is available in a 5 pin SOT-23 and 8-
pin SC70JW specified over -40 to 85°C.
The AAT4600 Series is a family of adjustable and
fixed SmartSwitch with a range of current han-
dling capabilities. Available are single versions in
adj. current limit (AAT4600, AAT4601) as well as in
fixed current limit (AAT4602, AAT4625). Dual ver-
sions (AAT4620, AAT4626) are also available.
