DESCRIPTION
The ACS110 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 1
A.
S
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.
