FEATURES

The ACS402 belongs to the AC line switches array family built around the ASD™ concept. This high performance planar technology device includes 4 bi-directional a.c. switches able to control an 0.2 A resistive or inductive load. Each ACS™ switch integrates a high voltage clamping structure to absorb the inductive turn off energy and a gate level shifter driver to separate the digital controller from each main switch. It is triggered with a negative gate current flowing out of the gate pin.

The ACS402 device is well adapted to washing machine, dishwasher, tumble drier, refrigerator, water heater and cookware. It has been designed especially to switch ON and OFF low power loads such as so- lenoid, valve, relay, micro-motor, pump, fan, door lock and low wattage lamp bulb. 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 Each ACS™ switch is triggered with a negative gate current flowing out of the gate pin G. It can be driven directly by the digital controller through a resistor as shown on the typical application diagram. Note that no protection device (zener or capacitors) should be added between gates and common terminals. In appliances systems, this ACS™ switch intends to drive low power load in full cycle ON / OFF mode. The turn off commutation characteristics of these loads can be classified in 3 groups as shown in table 1. Thanks to its thermal and turn off commutation performances, each switch of the ACS402 is able to drive an inductive or resistive load up to 0.2 A with no additional turn off snubber.

Each ACS402 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 3 is representative of the final ACS™ application and is also used to stress the ACS™ switch according to the IEC1000-4-5 standard conditions. Thanks to the load, the ACS™ switch sustains 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 4. Such non repetitive test can be done 10 times on each AC line voltage polarity.

Time (400µs/div) IOUT (10 mA/div) VOUT (200V/div) IH VCL = 650V 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 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 20 mJ and is dissipated in the clamping section that is especially designed for that purpose.
