FEATURES
The ACS108 belongs to the AC line switches built
around the ASD concept. This high performance
full planar technology device is able to control an
0.8 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.
DESCRIPTION
OUT
COMG
n Needs no more external protection snubber &
varistor.
n Enables the equipment to meet IEC1000-4-5
standard.
n Allows straightforward connection of several
SOT223 devices on the same cooling pad.
n Reduces the switch component count by up to
80%.
n Interfaces directly with the microcontroller.
n Eliminates any stressing gate kick back on the
microcontroller.
