Product details
Overview
SI86S622EE-AS4R from Skyworks Solutions is a dual-channel, high-speed digital isolator with reinforced 6000 VRMS isolation, 150 Mbps data rate, and AEC-Q100 qualification for automotive systems. It features Schmitt-trigger inputs, selectable fail-safe output (default low), and operates across 2.25–5.5 V supply rails. Used in battery management systems and traction inverters where galvanic separation of high-voltage control logic is critical.
For engineers reviewing the SI86S622EE-AS4R datasheet, SI86S622EE-AS4R pinout, SI86S622EE-AS4R application, or SI86S622EE-AS4R equivalent, this page delivers verified specifications, package mapping, functional context, and real-world design implications - including CMTI ≥100 kV/µs, 10 ns typical propagation delay, and SSO-8 automotive-grade packaging.
Technical Context
The SI86S622EE-AS4R implements RF-based on/off keying across a semiconductor isolation barrier, eliminating startup initialization and enabling robust noise immunity without optical degradation. Its dual-channel architecture supports independent side-A (VDD1/GND1) and side-B (VDD2/GND2) power domains with UVLO and reset circuitry per side.
It integrates input deglitch filters (36 ns), precise timing control (≤4.5 ns pulse width distortion), and failsafe operation via ordering option - here configured as default-low output during unpowered conditions. The device meets IEC 60747-17 reinforced insulation requirements and supports 150 Mbps operation at 2.5–5.5 V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | 150 Mbps - enables high-fidelity communication in fast-switching motor control and BMS state monitoring. |
| Propagation delay | 5–13.5 ns (typ. 9 ns) - ensures tight timing alignment between isolated control and feedback paths. |
| Isolation rating | 6000 VRMS (1 min) - certified for reinforced insulation in 600 VRMS working voltage systems per UL 1577. |
| CMTI | ≥100 kV/µs - maintains signal integrity during rapid common-mode transients in inverter gate drive circuits. |
| Supply range | 2.25–5.5 V - allows interoperability with 3.3 V microcontrollers and 5 V analog front-ends without level shifters. |
| Fail-safe mode | Default-low output - guarantees safe shutdown state when side-A supply is lost in automotive safety-critical functions. |
| Operating temp | –40 to +125 °C - qualified for under-hood and battery-pack environments per AEC-Q100 Grade 1. |
Pinout & Package
SI86S622EE-AS4R uses an SSO-8 (wide-body SOIC-8) package with 8.0 mm creepage/clearance, optimized for 6000 VRMS isolation and automotive reliability. Pin 1 = VDD1, Pin 2 = A1, Pin 3 = A2, Pin 4 = GND1, Pin 5 = GND2, Pin 6 = B1, Pin 7 = B2, Pin 8 = VDD2. NC pins are absent - all eight pins are functional.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, VDD2 | Independent power supplies | Enable true galvanic separation: side-A and side-B can operate at different voltages (e.g., 3.3 V MCU ↔ 5 V ADC). |
| GND1, GND2 | Isolated reference grounds | Prevent ground-loop currents; require separate PCB ground planes on each side of the isolation barrier. |
| A1, A2 | Digital inputs (side A) | Schmitt-trigger + CMOS threshold inputs tolerate noisy industrial bus signals without external conditioning. |
| B1, B2 | Digital outputs (side B) | 50 Ω nominal output impedance - matches controlled-impedance PCB traces for clean 150 Mbps eye diagrams. |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation | No startup initialization required; eliminates boot-time uncertainty in safety-critical automotive subsystems. |
| Input deglitch filter | 36 ns filtering removes sub-36 ns noise pulses - prevents false triggering in EMI-heavy motor drive environments. |
| Selectable fail-safe | Ordering option sets default output state (high/low); SI86S622EE-AS4R is default-low for fail-safe shutdown behavior. |
| AEC-Q100 Grade 1 | Qualified for –40 to +125 °C operation with full PPAP documentation support - meets automotive production requirements. |
| Reinforced insulation | UL 1577, VDE 60747-17, CSA 62368-1, CQC GB4943.1 certified - enables single-component isolation in medical and EV systems. |
Applications
| Onboard Charger Control | Battery Management System (BMS) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM220N0BRZ-RL7 | 5000 VRMS isolation, 150 Mbps, default-high fail-safe, SOIC-8 (narrow-body, 3.9 mm creepage) | Lacks AEC-Q100 qualification; not rated for automotive traction systems or onboard chargers above 400 V working voltage | Preferred for cost-sensitive industrial automation where 6000 VRMS and automotive qualification are not required. |
| ISO7721FDWR | 5000 VRMS, 100 Mbps, default-low fail-safe, SOIC-16 (wider footprint), no deglitch filter | Lower CMTI (85 kV/µs); lacks input noise filtering - requires external RC filtering in noisy motor control environments | Valid for non-safety-critical industrial ADC/DAC isolation where 100 Mbps suffices and board space permits SOIC-16. |
Compared with ADUM220N0BRZ-RL7 and ISO7721FDWR, SI86S622EE-AS4R uniquely combines 6000 VRMS reinforced insulation, AEC-Q100 Grade 1 qualification, integrated 36 ns deglitching, and SSO-8 packaging - making it the only option qualified for high-voltage automotive BMS and OBC designs requiring long-term reliability at 125 °C.

FAQ
What is the isolation voltage rating of SI86S622EE-AS4R?
SI86S622EE-AS4R is rated for 6000 VRMS isolation per UL 1577 (1 minute test), with reinforced insulation certification per VDE 60747-17 and CSA 62368-1. Its SSO-8 package provides 8.0 mm creepage and clearance, supporting up to 1500 VRMS working voltage in end equipment.
Does SI86S622EE-AS4R require external bypass capacitors?
Yes, SI86S622EE-AS4R requires 0.1 µF and 10 µF bypass capacitors on both VDD1-GND1 and VDD2-GND2 pairs. These must be placed as close as possible to the respective pins to suppress high-frequency noise and ensure stable RF transmitter/receiver operation.
What does the "EE" suffix indicate in SI86S622EE-AS4R?
The "EE" suffix denotes the SSO-8 package variant with enhanced creepage (8.0 mm) and AEC-Q100 qualification. It distinguishes SI86S622EE-AS4R from narrow-body NB SOIC-8 versions (e.g., SI86S622ED-AS4R) and confirms compliance with automotive PPAP and IMDS documentation requirements.
How does the fail-safe mode function in SI86S622EE-AS4R?
SI86S622EE-AS4R is configured as default-low: when side-A (input) supply is unpowered but side-B (output) remains powered, outputs B1 and B2 are actively driven low. This behavior is hard-coded by internal pull-down resistors and ensures safe shutdown in automotive fault conditions.
Can SI86S622EE-AS4R operate at 2.5 V supply?
Yes, SI86S622EE-AS4R supports 2.25–5.5 V operation on both sides. At 2.5 V, it maintains 150 Mbps data rate, 10 ns typical propagation delay, and full CMTI ≥100 kV/µs - validated per Table 8 in the datasheet for –40 to +125 °C ambient conditions.
