? Reduces component count

? Interfaces directly with the micro-controller

? High immunity against fast transients

described in IEC 61000-4-4 standards

Applications

? AC on/off static switching in appliances and

industrial control systems

? Driving low power highly inductive loads like

solenoid, pump, fan, and micro-motor

Description

The ACST2 series belongs to the ACS?/ACST

power switch family. This high performance

device is suited to home appliances or industrial

systems and drives loads up to 2 A.

This ACST2 switch embeds a Triac structure with

a high voltage clamping device to absorb the

inductive turn-off energy and withstand line

transients such as those described in the

IEC 61000-4-5 standards. The component needs

a low gate current to be activated (IGT < 10 mA)

and still shows a high electrical noise immunity

complying with IEC standards such as

IEC 61000-4-4 (fast transient burst test).
