DESCRIPTION

The AD4C211 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. Each integrated circuit is optically coupled to a light emitting diode. 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.
