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.
