Applications

AC ON/OFF static switching in appliances and industrial control systems Drive of low power high inductive or resistive loads like: relay, valve, solenoid, dispenser, door lock pump, fan, micro-motor

Description
The ACS108-6S belongs to the AC line switch family. This high performance switch can control a load of up to 0.8A. The ACS108-6S switch includes an overvoltage crowbar structure to absorb the overvoltage 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.

Benefits

Needs no external protection snubber or varistor. Enables equipment to meet IEC 61000-4-5. Reduces component count by up to 80%. Interfaces directly with the micro-controller. Common package tab connection supports connection of several alternating current switches (ACS) on the same cooling pad. Integrated structure based on ASD(a) technology
