This high performance device is able to control an up to 0.3 A load device. 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. For further technical information, please refer to AN1172 application note.

It has been designed especially to switch on & off low power loads such as solenoids, 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 directly 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. o r P Table 1: Low power load turn off commutation requirement (230V AC applications).
