DESCRIPTION
ACS108
The ACS108 belongs to the AC line switches built
around the ASD™ concept. This high performance
device is able to control an 0.8 A load device.
S
The 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 ACS108 device is well adapted to washing machines, dishwashers, tumble driers, refrigerators, water
heaters and cookware. It has been especially designed to switch ON and OFF low power loads such as
solenoids, valves, relays, dispensers, micro-motors, fans, pumps, door locks and low power lamp bulbs.
Pin COM:
Pin G:
Common drive reference to connect to the power line neutral
Switch Gate input to connect to the digital controller through the resistor
Switch Output to connect to the Load
Pin OUT:
The 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. No protection
devices are required between the gates and common terminals.
The SOT-223 version allows several ACS108 devices to be connected on the same cooling PCB pad
which is the COM pin : this cooling pad can be then reduced, and the printed circuit layout is simplified.
In appliance systems, the ACS108 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 characteristics, the ACS108 switch drives a load, such as
door lock, lamp, relay, valve and micro motor, up to 0.2 A without any turn-off aid circuit. Switching off the
ACS within one full AC line cycle will extend its current up to 0.8 A on resistive load.

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 section that is especially designed for that
purpose.

AC LINE TRANSIENT VOLTAGE RUGGEDNESS
The ACS108 switch is able to safely withstand the AC line transient voltages either by clamping the low en-
ergy spikes or by breaking over under high energy shocks.
The test circuit in Figure 4 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 resis-
tive load where the turn-on current rise is high as shown in Figure 4. Such non-repetitive testing can be
done 10 times on each AC line voltage polarity.

and inductive loads according to IEC61000-4-5
standard.
