ACS102-5Tx
AC LINE SWITCH BASIC APPLICATION
The ACS102 device is well adapted to washing machines, dish washers, tumble driers, refrigerators, water
heaters, and cookware. It has been designed especially to switch on & off low power loads such as sole-
noids, valves, relays, dispensers, micro-motors, pumps, fans, door locks, and low power lamps 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
This 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
device are required between the gate and COM terminals.
The SO-8 version allows to connect several ACS102 devices on the same cooling PCB pad which is the
COM pin.
In appliance systems, the ACS102 switch intends to drive low power loads in full cycle ON / OFF mode.
The turn off commutation characteristics of these loads are described in Table 1.
Thanks to its thermal and turn-off commutation characteristics, the ACS102 switch drives a load, such as
door lock, lamp, relay, valve and micro motor, up to 0.2A without any turn-off aid circuit. Switching off the
ACS within one full AC line cycle will extend its current up to 0.3 A.
