FEATURES

The ACS120 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 2 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 ACS120 device is well adapted to Washing machine, dishwasher, tumble drier, refrigerator, air-conditioning systems, and 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. Thanks to its thermal and turn off commutation performances, the ACS120 switch is able to drive with no turn off additional snubber an inductive load up to 2 A. AC LINE SWITCH BASIC APPLICATION OUT ACS120 COM G S D ON ST72 MCU N AC MAINS L R - Vcc L M LOAD TYPICAL APPLICATION DIAGRAM 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 then through the ava- lanche diode D and decreases linearly to zero. During this time, the voltage across the switch is limited to the clamping voltage V CL . The energy stored in the inductance of the load depends on the holding current IH and the inductance (up to 10 H); it can reach about 10 mJ and is dissipated in the clamping diode section. The ACS switch sustains the turn off energy because its clamping section is designed for that purpose. HIGH INDUCTIVE SWITCH-OFF OPERATION

Fig. A:Turn-off operation of the ACS120 switch with an electro-valve: waveform of the pin OUT current I OUT and voltage VOUT . VOUT IOUT VCL IH Fig. B:ACS120 switch static characteristic. The ACS120 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.
