Overview

The SI8641BB-B-IS is a high-performance, quad-channel digital isolator providing 2.5 kVrms isolation using Skyworks proprietary CMOS technology. It features three forward and one reverse channel, supporting data rates up to 150 Mbps with significantly lower propagation delay and jitter compared to traditional optocouplers.

Why Choose This Part

This device offers ultra-low power consumption of approximately 1.6 mA per channel at 1 Mbps, making it suitable for power-constrained designs. Its wide-body SOIC-16 package provides superior creepage and clearance distances for robust safety compliance in high-voltage environments.

Applications

Industrial Fieldbus Isolation
Protects sensitive microcontrollers from noise and ground loops in RS-485, CAN, and Profibus networks.
Isolated SPI Interface
The 3/1 channel configuration is ideal for SPI buses, providing isolation for SCLK, MOSI, and SS in one direction and MISO in the reverse.
Battery Management Systems
Safely bridges the high-voltage battery domain to the low-voltage control domain in EV or energy storage applications.
Motor Control Feedback
Transmits PWM signals and encoder feedback across the isolation barrier in high-power motor drives.

Getting Started

Integrate the device between two isolated power domains ensuring VDD1 and VDD2 are bypassed with 0.1 uF ceramic capacitors. No special proprietary tools are required, as the device operates as a standard logic buffer across the isolation barrier.
