AAT4601
1.5A Current Limited P-Channel Switch
General Description
The AAT4601 SmartSwitch™ is part of
AnalogicTech's Application Specific Power
MOSFET™ (ASPM™) product family. It is a 1.5A
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, making it ideal for both 3V and 5V sys-
tems. An integrated current-limiting circuit protects
the input supply against large changes in load cur-
rent which could cause the supply to fall out of reg-
ulation. The AAT4601 has protection from thermal
overload which limits power dissipation and junc-
tion temperatures. The maximum current limit
level is 1.5A; the actual threshold is programmed
with a resistor from the SET pin to ground. The qui-
escent supply current is typically 12µA. In shut-
down mode, the supply current decreases to less
than 1µA.
The AAT4601 is available in 8-pin SOP or TSSOP
specified over -40 to 85°C.

Printed Circuit Board Layout
Recommendations
For proper thermal management, and to take
advantage of the low RDS(ON) of the AAT4601, a few
circuit board layout rules should be followed: VIN
and VOUT should be routed using wider than normal
traces, and GND should be connected to a ground
plane. For best performance, CIN and COUT should
be placed close to the package pins.
Evaluation Board Layout
The AAT4601 evaluation layout follows the printed
circuit board layout recommendations, and can be
used for good applications layout.
Note: Board layout shown is not to scale.
