DESCRIPTION
The ACS102 belongs to the AC line switch family
built around the ASD鈩?concept. This high perfor-
mance device is able to control an up to 0.3 A load
device.
The ACS鈩?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.
