Functional Isolation, DC input, normally open output, single-channel isolated switch opto-emulator

The ISOM8600 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 ISOM8600 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. 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.
