Skyworks Solutions Inc. SI86S630EC-AS1R

Overview

SI86S630EC-AS1R from Skyworks Solutions is a 3-channel, reinforced digital isolator with 6000 VRMS isolation rating, 150 Mbps data rate, and AEC-Q100 qualification for automotive systems. It features Schmitt-trigger + CMOS inputs, tri-state outputs with enable, selectable fail-safe mode (default high/low), and operates across –40 to 125 °C in WB SOIC-16 package. It is used in battery management systems and traction inverters where high noise immunity and safety-certified signal isolation are required.

For engineers reviewing the SI86S630EC-AS1R datasheet, SI86S630EC-AS1R pinout, SI86S630EC-AS1R application, or SI86S630EC-AS1R equivalent, key selection criteria include reinforced IEC 60747-17 certification, 10 ns typical propagation delay, 3.5 ns pulse width distortion, transient immunity ≥100 kV/µs, and dual supply operation (2.25–5.5 V per side).

Technical Context

The SI86S630EC-AS1R implements RF-based on/off keying 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 on both sides (VDD1/VDD2), with RSTB thresholds at ~1.7 V and UVLO+ at 2.18 V.

It integrates tri-state output control via EN1/EN2 pins, configurable fail-safe output state during unpowered conditions, and supports sleep mode via external SMb pin (though not implemented in this specific ordering option). All channels share identical timing specs: 10 ns propagation delay, 3.5 ns pulse width distortion, and 100 kV/µs CMTI.

Key Specifications

Pinout & Package

SI86S630EC-AS1R is housed in a wide-body SOIC-16 (WB SOIC-16) package with creepage/clearance optimized for 6000 VRMS reinforced insulation. Pin 1 is marked with a dot; pin 16 is VDD2, pin 8 is GND1, and pin 9 is GND2. The isolation barrier separates Side A (pins 1–8) and Side B (pins 9–16).

FAQ

What is the isolation rating and safety certification status of SI86S630EC-AS1R?

SI86S630EC-AS1R provides 6000 VRMS isolation for 1 minute per UL 1577 and is certified to IEC 60747-17 (reinforced insulation). It also meets CSA 62368-1 and 60601-1, and CQC GB4943.1. These certifications are fully documented for automotive PPAP submission and end-system safety compliance.

Does SI86S630EC-AS1R require external bypass capacitors?

Yes, SI86S630EC-AS1R requires 0.1 µF and 10 µF ceramic bypass capacitors placed between VDD1–GND1 and VDD2–GND2, respectively. These must be mounted as close as possible to the package pins to ensure stable operation and meet EMC requirements in automotive environments.

What is the function of the EN1 and EN2 pins on SI86S630EC-AS1R?

EN1 and EN2 are active-high output enable pins controlling all outputs on Side A and Side B, respectively. When low, they place corresponding outputs in high-impedance (tri-state) mode-enabling shared bus topologies and power sequencing in multi-isolator systems using SI86S630EC-AS1R.

How does the fail-safe mode operate in SI86S630EC-AS1R?

SI86S630EC-AS1R uses the "E" suffix to indicate default-low fail-safe behavior: when VDD1 is unpowered but VDD2 remains active, all B1–B3 outputs default to logic low. This ensures safe shutdown of downstream power devices during controller-side brownout events.

Is SI86S630EC-AS1R compatible with 3.3 V and 5 V logic families?

Yes, SI86S630EC-AS1R supports 2.25–5.5 V on both sides independently. It accepts CMOS- and Schmitt-trigger-compatible inputs and drives outputs with VOH ≥ VDD–0.4 V and VOL ≤ 0.4 V-ensuring interoperability with 3.3 V MCUs and 5 V gate drivers without level-shifting circuitry.
