DESCRIPTION

The ACS102 belongs to the AC line switch family
built around the ASD concept. This high perfor­mance 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
anda gate levelshifter driver to separatethe digital
controller from the main switch. It is triggered with
anegative gate currentflowing out of thegate pin.

AC LINE SWITCH BASIC APPLICATION

The ACS102 device is well adapted to washing machine, dish washer, tumble drier, refrigerator, water
heaters, and cookware. It has been designed especially to switch on & off low power loads such as sole­noid, valve, relay, dispenser, micro-motor, pump, fan, door lock, and low wattage lamps bulbs.

PinCOM : Common drive reference to connect to the power line neutral
Pin G : Switch Gate input to connect to the digital controller through a resistor
Pin OUT : Switch Output to connect to the load

This ACS switch is triggered with a negative gate current flowing out of the gate pin G. It can be driven di­rectly by the digital controller through a resistor as shown on the typical application diagram. No protection
device (zener or capacitor) are required between gate and COM terminals.
The SO-8 version allows to connect several ACS102 devices on the same cooling PCB pad which is the
COM pin.
In appliances systems, the ACS102 switch intends to drive low power load in full cycle ON / OFF mode.
The turn off commutation characteristics of these loads are described in table 1.
Thanks to its thermal and turn off commutation performances, the ACS102 switch is able to drive with no
turn off aid snubber a load up to 0.2 A (door lock, lamp, relay, valve & micro motor) when this load has to
switch off withinone half AC line cycle, and up to 0.3 A (pump, fan) when this load can switch off within one
full AC line cycle.
