AD42211

www.DataSheet4U.com AD42211 2 Form A Solid State Relay DESCRIPTION The AD42211 is a bi-directional, double-pole, single-throw, normally open multipurpose solid-state relay. It is designed to replace electromechanical relays in general purpose switching applications. The relay consists of two integrated circuits, each driving a pair of rugged source-to-source enhancement type DMOS transistors. Both integrated circuits are optically coupled to one light emitting diode, which controls both switches. The output MOS transistors are protected with free-wheeling diodes that can handle up to 1.5A of inrush current, making the relay ideal for switching lamps and highly inductive loads.
