FEATURES
The ACS120 belongs to the AC line switch family
built around the ASD™ concept. This high perfor-
mance switch circuit is able to control a load up to 2
A.
The ACS™ switch embeds a high voltage clamp-
ing structure to absorb the inductive turn off energy
and a gate level shifter driver to separate the digital
controller from the main switch. It is triggered with
a negative gate current flowing out of the gate pin.
DESCRIPTION

G
n Needs no more external protection snubber or
varistor
n Enables equipment to meet IEC 61000-4-5
n Reduces component count up to 80 %
n Interfaces directly with the microcontroller
n Eliminates any gate kick back on the
microcontroller
n Allows straightforward connection of several
ACS™ on same cooling pad.
