TheACS102 device iswell adapted towashing machines, dishwashers, tumble driers,refrigerators, water

heaters, and cookware. It has been designed especially to switch on & off low power loads such as sole-

noids, valves, relays, dispensers, micro-motors, pumps, fans, door locks, and low power lamps bulbs.

Pin COM : 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

ThisACS™ switch istriggered with anegative gatecurrent flowing outof the gatepin G. Itcan be drivendi-

rectly by the digital controller through a resistor as shown on the typical application diagram. No protection

device are required between the 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 appliance systems, the ACS102 switch intends to drive low power loads 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 characteristics, the ACS102 switch drives a load, such as

door lock, lamp, relay, valve and micro motor, up to 0.2A without any turn-off aid circuit. Switching off the

ACS within one full AC line cycle will extend its current up to 0.3 A.

At the end of the last conduction half-cycle, the load current reaches the holding current level IH, and the

ACS™ switch turns off. Because of the inductance L of the load, the current flows through the avalanche

diode D and decreases linearly to zero. During this time, the voltage across the switch is limited to the

clamping voltage VCL.

The energy stored in the inductance of the load depends on the holding current IHand the inductance (up

to 10 H); it can reach about 20 mJ and is dissipated in the clamping diode section. The ACS™ switch sus-

tains the turn off energy, because its clamping section is designed for that purpose.

TheACS102 switchis ableto withstandsafely theAC linetransient voltages either by clamping the low en-

ergy spikes or by breaking over under high energy shocks.

The test circuit of the figure 3 is representative of the final ACS™ application and is also used to stress the

ACS™ switch according to the IEC61000-4-5 standard conditions. Thanks to the load, the ACS™ switch

withstandsthe voltagespikes up to2 kVabove the peak line voltage.It willbreak over safely even onresis-

tive load where the turn on current rate of increase is high as shown on figure 4. Such non repetitive test

can be done 10 times on each AC line voltage polarity.
