AAT4625
USB Single-Channel Power Switch
General Description
The AAT4625 SmartSwitch™ is part of
AnalogicTech's Application Specific Power
MOSFET™ (ASPM™) product family. It is a 1.0A
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 systems.
An integrated current-limiting circuit protects the
input supply against large changes in load current
which may cause the supply to fall out of regulation.
The AAT4625 is also protected from thermal over-
load which limits power dissipation and junction
temperatures. The current limit threshold is factory
programmed at 1.5A, with a maximum of 2.0A. The
quiescent supply current is typically a low 16µA. In
shutdown mode, the supply current decreases to
less than 1µA.
The AAT4625 is available in 8 pin SOP or TSSOP
and is specified over a -40 to 85°C temperature
range.
The AAT4600 Series is a family of adjustable and
fixed SmartSwitch™ products with a range of cur-
rent handling capabilities. Single versions with
adjustable current limit (AAT4601) or fixed current
limit (AAT4625) as well as dual versions with fixed
current limit (AAT4626) are available.
