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.
ASD and ACS are trademarks of STMicroelectronics.

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 drivereference, to connect
to the power line neutral Pin G: Switch Gate inputto 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 thegate 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
threeloads up to 0.2A each,as, for example, two watervalves and a door lockin a dishwasher, without any additionnal turn-off snubber.
