II. Skyworks Isolation Technology: Leading CMOS Silicon Isolation Solutions

Skyworks is a global leader in isolation technology. Leveraging its patented CMOS capacitive isolation technology, it offers an alternative to traditional optocoupler solutions, delivering core advantages such as high isolation voltage, high-speed data transmission, high immunity to interference, low power consumption and long service life. With isolation voltages of up to 6kVrms and common-mode transient immunity (CMTI) exceeding 200kV/μs, these solutions are widely deployed in demanding applications across the automotive, industrial and medical sectors.

III. Detailed Overview of Core Product Series

(1) Automotive Isolators: Automotive-grade safety, compliant with ISO 26262 functional safety

Designed specifically for new energy vehicles and intelligent driving, these products comply with the AEC-Q100 automotive-grade standard and ISO 26262 functional safety requirements. They withstand a wide temperature range of -40°C to 125°C, ensuring the safe signal isolation of on-board high-voltage systems (such as BMS, OBC and motor controllers).

Core Applications: New energy vehicle battery management systems (BMS), on-board chargers (OBC), DC/DC converters, electric drive inverters, autonomous driving domain controllers, and in-vehicle CAN/LIN bus isolation.

Key Advantages: High isolation voltage (up to 5kVrms), low propagation delay, strong EMI immunity, support for ASIL-B/D safety levels, and elimination of high-voltage crosstalk risks.

(2) Digital Isolators: High-speed and stable, with flexible multi-channel adaptability

Covering classic series such as the Si80xx, Si86xx and Si88xx, these provide 1–6-channel unidirectional/bidirectional signal isolation. With high integration and compact dimensions, they are the perfect replacement for traditional optocouplers.

Si86xx High-Speed Series: With communication rates up to 100Mbps, isolation voltage of 2.5–5kVrms, and CMTI of 150kV/μs, this series is suitable for isolating high-speed buses such as SPI, I2C and RS-485.

Si88xx Integrated Power Series: Featuring a built-in 2W isolated DC-DC converter, this single-chip solution achieves simultaneous ‘signal + power’ isolation, significantly simplifying circuitry and reducing PCB footprint, making it ideal for space-constrained industrial and automotive designs.

Si87xx Optocoupler Replacement Series: Pin-compatible with traditional optocouplers, these devices reduce power consumption by 90%, extend lifespan by 10 times, and offer superior cost efficiency.

(3) Isolated Field-Effect Transistor (FET) Drivers: High-current drive and efficient protection for power devices

Centred on the Si82xx and Si875x series, these are specifically designed to drive MOSFETs, IGBTs, and SiC/GaN wide-bandgap devices. They provide robust drive currents of 1A–6A, enabling precise control of power switches and enhancing system efficiency.

Si82Fx Current-Mode Series: Utilising the patented SelVCD™ architecture, it supports 200 kV/μs CMTI and 6 kVrms isolation. It optimises switching losses without the need for external gate resistors and is compatible with silicon carbide (SiC) and gallium nitride (GaN) devices.

Si82Bx/Ex Voltage-Mode Series: A versatile, cost-effective solution compatible with IGBTs and traditional MOSFETs, featuring under-voltage lockout (UVLO) and overcurrent protection to ensure the safety of power circuits.

Si875x Isolated FET Drivers: Designed specifically as a replacement for relays, offering low power consumption and high isolation, suitable for industrial I/O and smart control applications.

(4) Isolated Transceivers: Bus isolation for stable communication

At the core is the Si858x series of isolated CAN/RS-485 transceivers, which integrate isolation and bus communication functions, enabling protocol conversion and electrical isolation within a single chip.

Isolated CAN Transceivers: Supports high-speed CAN FD communication (up to 5 Mbps), with an isolation voltage of 5 kVrms and a bus voltage tolerance of ±36 V. Features ESD protection and surge suppression, suitable for automotive CAN buses and industrial CANopen networks.

Isolated RS-485 Transceiver: Half-duplex communication, data rates up to 50 Mbps, wide common-mode voltage range, strong interference immunity, suitable for industrial fieldbus and long-distance data transmission.

IV. Typical Application Scenarios

New Energy Vehicles: BMS high-voltage sampling isolation, OBC/DC-DC driver isolation, in-vehicle CAN bus communication isolation, and IGBT driver protection for electric drive systems.

Industrial Automation: PLC digital I/O isolation, servo motor drive control, industrial robot bus communication, photovoltaic inverters, and power conversion systems (PCS).

Smart Grid: Smart meters, power monitoring equipment, high-voltage sensor signal isolation, and UPS (uninterruptible power supply).
