■ Interfaces directly with the microcontroller

■ Direct interface with the microcontroller for the

ACST4-7S (I_GT< 10 mA)

COM

Description

The ACST4 belongs to the AC power switch

family built around the ASD™ technology. This

high performance device is adapted to home

appliances or inductrial systems and drives loads

up to 4 A.

The ACS™ 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.
