Applications
Description
■ AC ON/OFF static switching in appliances and
industrial control systems
The ACS108-6S belongs to the AC line switch
family. This high performance switch can control a
load of up to 0.8A.
■ Drive of low power high inductive or resistive
loads like:
– relay, valve, solenoid,
– dispenser, door lock
– pump, fan, micro-motor
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.
Functional diagram
■ Enables equipment to meet IEC 61000-4-5.
■ Reduces component count by up to 80%.
■ Interfaces directly with the micro-controller.
OUT
■ Common package tab connection supports
connection of several alternating current
switches (ACS) on the same cooling pad.
■ Integrated structure based on ASD(1)
