General Description
The AAT4250 SmartSwitch™ is a member of
AATI's Application Specific Power MOSFET™
(ASPM™) product family. It is a Slew Rate
Controlled P-channel MOSFET power switch
designed for high-side load-switching applications.
This switch operates with an input voltage range
from 1.8V to 5.5V, making it ideal for 2.5V, 3.3V or
5V systems. The part features 1.5ms turn on and
10µs turn off time. The AAT4250 has an under volt-
age lock out which turns off the switch when an
under-voltage condition exists. Input logic levels
are TTL compatible. The quiescent supply current
is very low, typically 2µA. In shutdown mode, the
supply current is typically reduced to 0.1µA or less.
The AAT4250 is available in a 5-pin SOT23 and 8-
pin SC70JW specified over -40 to 85°C.
