FEATURES
The ACS110 belongs to the AC line switch family built around the ASD™ concept. This high perfor- mance switch circuit is able to control a load up to 1 The ACS™ switch embeds a high voltage clamp- ing 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.

The ACS110 device is well adapted to Washing machine, dishwasher, tumble drier, refrigerator, water heaters,air-conditioning systems, microwave ovens and other cookware. It has been designed especially to switch on & off low power loads such as solenoid, valve, relay, dispenser, micro-motor, pump, fan and defrost heaters. Pin COM: Common drive reference to connect to the power line neutral Pin G: Switch Gate input to connect to the digital controller 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 di- rectly by the digital controller through a resistor as shown on the typical application diagram. Several ACS110 devices can be connected on the same cooling PCB pad, which is the COM pin. Thanks to its thermal and turn off commutation performances, the ACS110 switch is able to drive with no turn off additional snubber an inductive load up to 1 A.

The ACS110 switch is able to sustain safely the AC line transient voltages either by clamping the low en- ergy spikes or by breaking over under high energy shocks, even with high turn-on current rises. The test circuit of the figure C is representative of the final ACS application and is also used to stress the ACS switch according to the IEC 61000-4-5 standard conditions. Thanks to the load, the ACS switch sus- tains the voltage spikes up to 2 kV above the peak line voltage. It will break over safely even on resistive load where the turn on current rise is high as shown on figure D. Such non repetitive test can be done 10 times on each AC line voltage polarity.
