DESCRIPTION

The AD4C111-L is a bi-directional, double-pole, single-throw, normally open solid-state relay. The combination of high load voltage, low

on-resistance, and current limit protection make the AD4C311-L a unique device.

The AD4C111-L combines two optically isolated, discrete, current limit protected SSRs in one compact 8 pin DIP/SMD package. Each

SSR is composed of an IR LED, optically coupled to an IC, which in turn drives back-to-back MOSFETs on the output. The IC provides

current limit protection. During transient current spikes, this circuitry limits the current on the output of the device, thereby offering an

additional measure of protection to itself and downstream components.
