3 Description

The ISOM8610 is an 80V single-pole, normally-

open switch with an opto-emulator input. The opto-

emulator inputs control the back-to-back MOSFETs

without any power supply required on the secondary

side. The devices are pin-compatible and drop-

in replaceable for many traditional optocouplers,

allowing enhancement to industry-standard packages

with no PCB redesign.

The ISOM8610 opto-emulator switch offers significant

reliability and performance advantages compared

to optocouplers, like wider temperature ranges

and tight process controls resulting in small part-

to-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. ISOM8610 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 ISOM8610 is offered in a small SO-4 package,

supporting a 3.75kV

RMS

isolation rating. 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.
