3 Description

The ISOM8600 is an 80V single-pole, normallyopen

switch with an opto-emulator input. The optoemulator

inputs control the back-to-back MOSFETs

without any power supply required on the secondary

side. The devices are pin-compatible and dropin

replaceable for many traditional optocouplers,

allowing enhancement to industry-standard packages

with no PCB redesign.

The ISOM8600 opto-emulator switch offers significant

reliability and performance advantages compared

to optocouplers, like wider temperature ranges

and tight process controls resulting in small partto-

part variations. Since there is no aging effect

to compensate for, the emulated diode-input stage

consumes less power than optocouplers that have

LED aging and require higher bias currents over

the device lifetime. ISOM8600 switch output can

be controlled by just 0.8mA current through anode/

cathode pins over the lifetime of the device, enabling

system power savings.

The ISOM8600 is offered in a small SO-4 package,

supporting a 500VRMS functional isolation. The

high performance and reliability of the device

enable the devices use in applications like Building

automation, Factory automation, Semiconductor

test, I/O modules in industrial controllers, factory

automation applications, and more spaces.
