TYPICAL APPLICATION DIAGRAM
The ACS402 device is well adapted to washing machines, dishwashers, tumble driers, refrigerators, water
heaters and cookware. It has been designed especially to switch ON and OFF low power loads such as so-
lenoids, 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 the 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 protec-
tion device are required between the gates and common terminals.
In appliance 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 performance, 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.
