AAT4280
Slew Rate Controlled Load Switch
General Description
The AAT4280 SmartSwitch鈩?is a member of AATI's
Application Specific Power MOSFET鈩?(ASPM鈩?
product family. The AAT4280 is a P-channel MOS-
FET power switch designed for high-side load-
switching applications. The P-channel MOSFET
device has a typical R
DS(ON)
of 80m鈩? allowing
increased load switch power handling capacity. This
device is available in three different versions with
flexible turn on and off characteristics from very fast
to slew rate limited. The standard AAT4280 (-1) ver-
sion has a slew rate limited turn on load switch and
is functionally compatible with the AAT4250 device
while offering superior R
DS(ON)
characteristics. The
AAT4280 (-2) version features fast load switch turn
on capabilities, typically less than 210ns turn on and
3碌s turn off times. The AAT4280 (-3) variation offers
a shutdown load discharge circuit to rapidly turn off
a load circuit when the switch is disabled. All
AAT4280 load switch versions operate with an input
voltage ranging from 1.8V to 5.5V, making them
ideal for both 3V and 5V systems. The AAT4280
also features an under voltage lock out which turns
the switch off when an input under-voltage condition
exists. Input logic levels are TTL and 2.5 volt to 5
volt CMOS compatible. The quiescent supply cur-
rent is very low, typically 2.5碌A(chǔ). In shutdown mode,
the supply current decreases to less than 1碌A(chǔ).
The AAT4280 is available in a 6 pin SOT23 or 8
pin SC70JW package and is specified over -40擄C
to 85擄C temperature range.
