FEATURESThe ACS108 belongsto the AC line switches built
around the ASD™ concept. This high performance
deviceis ableto controlan 0.8A load device.
The ACS™ switch embedsa high voltage
clamping structure to absorb the inductive
turn-off energy anda gate level shifter driverto
separate the digital controller from the main
switch.Itis triggered witha negative gate current
flowing outof the gate pin.
For further technical information, please referto
AN1172 the Application note.
DESCRIPTION Needsno external overvoltage protection. Enables the equipmentto meet IEC61000-4-5
standard. Allows straightforward connection of several
SOT-223 deviceson the same cooling pad. Reduces the switch component count by upto
80%. Interfaces directly with the microcontroller. Eliminates any stressing gate kick back on the
microcontroller.

ACS108-5SxThe ACS108 deviceis well adaptedto washing machines, dishwashers, tumble driers, refrigerators, water
heaters and cookware.It has been especially designedto switch ON and OFF low power loads suchas
solenoids, valves, relays, dispensers, micro-motors, fans, pumps, door locks and low power lamp bulbs.
Pin COM: Common drive referenceto connectto the power line neutral
PinG: Switch Gate inputto connectto the digital controller through the resistor
Pin OUT: Switch Outputto connectto the Load
The 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
devices are required between the gates and common terminals.
The SOT-223 version allows several ACS108 devicesto be connected on the same cooling PCB pad
whichis the COM pin: this cooling pad canbe then reduced, and the printed circuit layoutis simplified. appliance systems, the ACS108 switch intendsto drive low power loadin full cycle ON/ OFF mode. The
turnoff commutation characteristicsof these loads canbe classifiedin3 groupsas shownin Table1.
Thankstoits thermal and turn-off commutation characteristics, the ACS108 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 0.8Aon resistive load.

Fig.2: ACS108 switch static characteristic. 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 theholding currentIH and the inductance (upto H);it can reach about20 mJ andis dissipatedin the clamping section thatis especially designedfor that
purpose.
HIGH INDUCTIVE SWITCH-OFF OPERATIONThe ACS108 switchis ableto safely withstand the AC line transient voltages eitherby clamping the low en-
ergy spikesorby breaking over under high energy shocks.
The test circuitin Figure4is 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 turn-on current riseis highas shownin Figure4. Such non-repetitive testing canbe
done10 timeson each AC line voltage polarity.
