ACS402-5SB4
3/6
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.
