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 3.75kVRMS 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.
