Features
• Enables equipment to meet IEC 61000-4-5 surge with overvoltage crowbar technology
• High noise immunity against static dV/dt and IEC 61000-4-4 burst • Needs no external protection snubber or varistor • Reduces component count by up to 80% and Interfaces directly with the micro-
controller • Common package tab connection supports connection of several alternating
current switches on the same cooling pad • VCL gives headroom before clamping then crowbar action
Applications
• Alternating current on/off static switching in appliances and industrial control systems
• Driving low power high inductive or resistive loads like: – relay, valve, solenoid, dispenser – pump, fan, low power motor, door lock, air flow dumper – lamp
Description
The ACS108-6SA belongs to the AC switch range (built with A. S. D.® technology). This high performance switch can control a load of up to 0.8 A.
This device switch includes an overvoltage crowbar 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.
