Analogic AAT4625IHS-T1 Usb single-channel power switch Datasheet

AAT4625
USB Single-Channel Power Switch
Features
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 overload 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 current 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.
