Description

The ACS108 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. The ACS108 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.

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

VCLgives 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

–lamp
