Overview

The Si86P542BC-IS is a high-performance, 4-channel digital isolator with an integrated DC-DC converter that provides isolated power. It offers 3.75kVrms isolation and supports data rates up to 150Mbps, making it ideal for high-speed signal isolation in systems requiring a compact footprint. The device features 2 forward and 2 reverse channels, simplifying bidirectional communication like SPI in space-constrained designs.

Why Choose This Part

This isolator eliminates the need for a separate isolated power supply, significantly reducing PCB area and BOM complexity. With a high CMTI of 100kV/us and low 15ns propagation delay, it ensures reliable data integrity in electrically noisy industrial environments.

Applications

Isolated SPI Communication
Providing high-speed data isolation and integrated power for sensors and ADCs on a galvanically isolated bus.
Industrial Automation
Protecting logic-side controllers from high-voltage transients in programmable logic controllers (PLCs) and motor drives.
Power Supply Control
Providing feedback signals and bias power across the primary-secondary isolation barrier in switch-mode power supplies.
