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.
