DESCRIPTION
The ACS302 belongs to the AC line switch family
built around the ASD™ concept. This high
performance device inludes 3 bidirectionnal AC
switches able to control an 0.2A resistive or
inductive load device.
Each ACS™ switch embeds a high voltage
clamping 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.

AC LINE SWITCH BASIC APPLICATION
The ACS302 device is well adapted to washing
machines, dishwashers, tumble driers, refrigerators, water heaters, and cookwares. It has been
designed especially to switch ON & OFF low
power loads such as solenoids, valves, relays, micro-motors, pumps, fans, door locks and low
power lamp bulbs.

Pin COM: Common drive reference, to connect
to the power line neutral
Pin G: Switch Gate input to connect to the digital
controller through a resistor
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. No protection devices are required
between the gates and common terminals.
In appliances systems, this ACS™ switch intends to drive low power loads in full cycle ON / OFF mode.
Thanks to its thermal and turn off commutation performances, the ACS302-5TA switch is able to drive
three loads up to 0.2A each, as, for example, two water valves and a door lock in a dishwasher, without any
additionnal turn-off snubber.

HIGH INDUCTIVE SWITCH-OFF OPERATION
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 VCL.
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 diode section that is especially designed
for that purpose.

AC LINE TRANSIENT VOLTAGE RUGGEDNESS
The ACS302 switch is able to withstand safely the AC line transient voltages either by clamping the low energy spikes or by breaking over under high energy shocks.
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 IEC61000-4-5 standard conditions. Thanks to the load, the ACS™ switch
withstands 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.
