FEATURESThe ACS102 belongsto the AC line switch family
built around the ASD™ concept. This high perfor-
mance deviceis ableto controlanupto 0.3A load

The ACS™ switch embedsa high voltage clamp-
ing structureto absorb the inductive turnoff energy
anda gate level shifter driverto separate the digital
controller from the main switch.Itis triggered with negative gate current flowingoutof the gate pin.

ACS102-5TxThe ACS102 deviceis well adaptedto washing machines, dish washers, tumble driers, refrigerators, water
heaters, and cookware.It has been designed especiallyto switchon&off low power loads suchas sole-
noids, valves, relays, dispensers, micro-motors, pumps, fans, door locks, and low power lamps bulbs.
Pin COM: Common drive reference,to connectto the power line neutral
PinG : Switch Gate inputto connectto the digital controller througha resistor
Pin OUT : Switch Output,to connectto the load
This ACS™ switchis triggered witha negative gate current flowing outof the gate pinG.It canbe drivendi-
rectlyby the digital controller througha resistoras shownon the typical application diagram. No protection
device are required between the gate and COM terminals.
The SO-8 version allowsto connect several ACS102 deviceson the same cooling PCB pad whichis the
COM pin. appliance systems, the ACS102 switch intendsto drive low power loadsin full cycle ON/ OFF mode.
The turnoff commutation characteristicsof these loads are describedin Table1.
Thankstoits thermal and turn-off commutation characteristics, the ACS102 switch drivesa load, suchas
door lock, lamp, relay, valve and micro motor,upto 0.2A without any turn-off aid circuit. Switchingoff the
ACS within one full AC line cycle will extendits currentupto 0.3A.
LINE SWITCH BASIC APPLICATION
Table1: Low power load turnoff commutation requirement (230V AC applications).
TYPICAL APPLICATION DIAGRAM
ACS102-5Tx the endof the last conduction half-cycle, the load current reaches the holding current levelIH, and the
ACS™ switch turns off. Becauseof the inductanceLof the load, the current flows through the avalanche
diodeD and decreases linearlyto zero. During this time, the voltage across the switchis limitedto the
clamping voltage VCL.
The energy storedin the inductanceof the load dependson the holding currentIH and the inductance (up10 H);it can reach about20 mJ andis dissipatedin the clamping diode section. The ACS™ switch sus-
tains the turnoff energy, becauseits clamping sectionis designedfor that purpose.

Fig.2: ACS102 switch static characteristic.
The ACS102 switchis ableto withstand safely the AC line transient voltages eitherby clamping the low en-
ergy spikesorby breaking over under high energy shocks.
The test circuitof the figure3is representativeof the final ACS™ application andis also usedto stress the
ACS™ switch accordingto the IEC61000-4-5 standard conditions. Thanksto the load, the ACS™ switch
withstands the voltage spikesupto2kV above the peak line voltage.It will break over safely evenon resis-
tive load where the turnon current rateof increaseis highas shownon figure4. Such non repetitive test
canbe done10 timeson each AC line voltage polarity.
