Description

The ACS120 belongs to the AC line switch family.

This high-performance switch circuit is able to

control a load of up to 2 A.

The ACS switch embeds a high-voltage clamping

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.
