ACS102
DESCRIPTION
The ACS102 belongs to the AC line switch family
built around the ASD concept. This high perfor-
mance 5 mA switch circuit is able to control an up
to 0.3 A load.
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.
