Skyworks Solutions Inc. SI86S662BE-IS2R

Overview

SI86S662BE-IS2R from Skyworks Solutions is a 6-channel reinforced digital isolator with 6000 VRMS isolation, 150 Mbps data rate, and dual 2.25–5.5 V supply operation. It features Schmitt-trigger inputs, tri-state outputs with enable, selectable fail-safe (default high/low), and operates across –40 to 125 °C for automotive battery management and industrial motor control systems.

For engineers reviewing the SI86S662BE-IS2R datasheet, SI86S662BE-IS2R pinout, SI86S662BE-IS2R application, or SI86S662BE-IS2R equivalent, key selection criteria include reinforced IEC 60747-17 certification, 10 ns propagation delay, 3.5 ns pulse width distortion, transient immunity ≥100 kV/µs, and AEC-Q100 qualification for traction inverter and onboard charger designs.

Technical Context

The SI86S662BE-IS2R implements RF-based on/off keying modulation across a semiconductor isolation barrier-eliminating start-up initialization and enabling robust noise immunity without optical degradation. Its architecture supports independent UVLO and reset monitoring per side (VDD1/VDD2), with 100 kΩ weak pulldown during unpowered states and configurable fail-safe output behavior.

It delivers bidirectional channel operation with six isolated I/O pairs (A1–A6/B1–B6), active-high EN1/EN2 enables per side, and operates in standard or low-power modes. The device supports SPI-compatible signaling when configured as part of Si86SSx variants but SI86S662BE-IS2R itself is a general-purpose 6-channel isolator-not an SPI-dedicated variant.

FAQ

What is the isolation voltage rating of the SI86S662BE-IS2R?

The SI86S662BE-IS2R has a reinforced isolation rating of 6000 VRMS for 1 minute per UL 1577, certified to IEC 60747-17, and supports working voltages up to 1200 V peak in end-system applications. This rating is validated for the WB SOIC-16 package and applies across the full –40 to 125 °C operating range.

Does the SI86S662BE-IS2R require external configuration or initialization at power-up?

No, the SI86S662BE-IS2R uses RF-based on/off keying and requires no start-up initialization. Outputs become valid within 0.3 ms after VDD exceeds the UVLO+ threshold (2.18 V typical), and internal weak pulldowns hold outputs low until stabilization-ensuring deterministic behavior in safety-critical systems.

What is the propagation delay and pulse width distortion specification for SI86S662BE-IS2R?

The SI86S662BE-IS2R has a typical propagation delay of 10 ns and typical pulse width distortion of 3.5 ns at VDD = 5.0 V and TA = 25 °C. These values are guaranteed across temperature and supply voltage ranges, enabling precise timing in motor control PWM and encoder interfaces.

Is the SI86S662BE-IS2R qualified for automotive applications?

Yes, the SI86S662BE-IS2R is AEC-Q100 qualified (Grade 1, –40 to 125 °C), with AIAG-compliant PPAP documentation, IMDS/CAMDS listing support, and manufacturing flows optimized for automotive defectivity targets-making it suitable for onboard chargers, battery management, and traction inverters.

What package type and footprint does the SI86S662BE-IS2R use?

The SI86S662BE-IS2R uses a WB SOIC-16 (wide-body small-outline integrated circuit) package with 10.3 mm creepage and clearance, RoHS-compliant finish, and pin-compatible layout with industry-standard SOIC-16 footprints-enabling drop-in replacement in existing designs requiring enhanced isolation.
