Functional Description
The AAT4295/97 is comprised of three or six low-
side N-channel MOSFET load switches primarily
targeted for general purpose applications where
several load circuits need to be connected to a com-
mon ground and controlled from a single microcon-
troller GPIO output. When a given switch is
enabled, the respective switch connects the load
input (S1 to S3 for the AAT4295 and S1 to S6 for the
AAT4297) to ground through the N-channel MOS-
FET. Each low-side N-channel MOSFET transistor
has a typical on resistance (R
DS(ON)
) of 2
when
operating from a 3.6V supply. Both the AAT4295
and AAT4297 have been designed to operate with
an input voltage range of 1.8V to 5.5V, making them
ideal for battery-powered applications.
These devices may be used for load switching
applications such as RGB LED fashion lighting,
display or keypad backlight LEDs, miscellaneous
indicator LED lamps, as well as audio and RF cir-
cuits or any other system with a power requirement
that does not exceed the thermal dissipation limits
of the load switch and device package.
Each switch input may be represented by the fol-
lowing circuit (Figure 1) and simplified equivalent
model (Figure 2).
