Each ACS鈩?switch integrates a high voltage
clamping structure to absorb the inductive turn off
energy and a gate level shifter driver to separate
the digital controller from each main switch. It is
triggered with a negative gate current flowing out
of the gate pin.

BENEFITS
n
Miniaturizes 4 switches in 1 package.
n
Reduces the switch component count by up to 80%.
n
Needs no more external protection snubber &
varistor.
n
Enables the equipment to meet IEC1000-4-5
standard.
n
Interfaces directly with the microcontroller.
n
Eliminates any stressing gate kick back on the
microcontroller.
DESCRIPTION
The ACS402 belongs to the AC line switches array
family built around the ASD鈩?concept. This high
performance planar technology device includes 4
bi-directional a.c. switches able to control an 0.2 A
resistive or inductive load.
