Automotive, DC-input transistor-output single-channel opto-emulator with 150% to 230% CTR

The ISOM811x-Q1 devices

are single-channel optocoupler-emulators with LED-emulator input and transistor

output. The devices are footprint compatible and pin-to-pin upgrades for many

traditional optocouplers, allowing enhancement to existing systems with no PCB

redesign.

ISOM811x-Q1

opto-emulators offer significant reliability and performance advantages compared to

optocouplers, including high bandwidth, low turn-off delay, low power consumption,

wider temperature ranges, flat CTR, and tight process controls resulting in small

part-to-part skew. Since there is no aging effect or temperature variation to

compensate for, the emulated LED input stage consumes less power than

optocouplers.

ISOM811x-Q1 devices are

offered in small SOIC-4 packages with 2.54mm and 1.27mm pin pitches, supporting

3750VRMS and 5000VRMS isolation

ratings with DC (ISOM811[0-3]-Q1) and bidirectional DC

(ISOM811[5-8]-Q1) input options. The high

performance and reliability of ISOM811x-Q1 enables these

devices to be used in power supply feedback design, motor drives, I/O modules in

industrial controllers, factory automation applications, and more.
