Product details
Overview
SI86S663BB-AUR from Skyworks Solutions is a 6-channel reinforced digital isolator with bidirectional signal isolation across a semiconductor barrier, supporting up to 150 Mbps data rate, 10 ns typical propagation delay, and 6000 VRMS isolation rating. It operates from 2.25–5.5 V on both sides and is qualified to AEC-Q100 for automotive traction inverters and battery management systems.
For engineers reviewing the SI86S663BB-AUR datasheet, SI86S663BB-AUR pinout, SI86S663BB-AUR application, or SI86S663BB-AUR equivalent, key selection criteria include its 6-channel configuration with independent enable pins (EN1/EN2), fail-safe default-high/low output option, Schmitt-trigger + CMOS input thresholds, and compliance with IEC 60747-17 reinforced insulation for high-noise industrial and automotive environments.
Technical Context
The SI86S663BB-AUR implements RF-based on/off keying modulation across a monolithic semiconductor isolation barrier, eliminating startup initialization and enabling robust noise immunity (100 kV/µs CMTI) without optical degradation concerns. Its architecture supports independent power domains (VDD1/GND1 and VDD2/GND2) with side-specific undervoltage lockout (UVLO) and reset (RSTB) thresholds.
It features tri-state outputs controlled by EN1 and EN2, selectable fail-safe mode (default high or low during unpowered conditions), and precise timing performance: 10 ns typical propagation delay, 3.5 ns pulse width distortion, and 36 ns input deglitch filtering available in select variants-though not specified for SI86S663BB-AUR per ordering code.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 150 Mbps - supports high-speed serial interfaces including isolated SPI and QSPI bus extensions. |
| Isolation Rating | 6000 VRMS for 1 minute - meets reinforced insulation requirements per UL 1577 and IEC 60747-17 for safety-critical automotive and industrial applications. |
| Propagation Delay | 10 ns typical - enables tight timing budgets in motor control gate drivers and real-time feedback loops. |
| Supply Voltage | 2.25–5.5 V per side - allows interoperability with 3.3 V and 5 V logic families on both isolated sides without level-shifting. |
| Operating Temperature | –40 to +125 °C - qualified for under-hood automotive use and industrial automation environments. |
| CMTI | ≥100 kV/µs - ensures reliable operation in high-dV/dt noise environments such as inverters and SMPS. |
| AEC-Q100 Grade | Qualified - confirms manufacturing flow and reliability validation for automotive-grade deployment. |
Pinout & Package
SI86S663BB-AUR is housed in a WB SOIC-16 package (wide-body, 10.3 mm creepage/clearance), supporting 6000 VRMS isolation. Pin assignments follow the Si86S66x family layout with six bidirectional channels and dual enable inputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Side A power supply | Provides independent 2.25–5.5 V domain for primary-side logic; requires local 0.1 µF + 10 µF bypassing. |
| A1–A6 | Side A digital I/O | Six bidirectional isolated channels; compatible with CMOS/Schmitt-trigger logic levels on Side A. |
| EN1 | Side A output enable | Active-high control: drives all A-side outputs into high-impedance when low; no internal pull-up. |
| VDD2, GND2 | Side B power supply | Independent secondary-side supply domain; electrically isolated from VDD1/GND1. |
| B1–B6 | Side B digital I/O | Corresponding six isolated channels on secondary side; fully decoupled from Side A timing and voltage. |
| EN2 | Side B output enable | Active-high control: places all B-side outputs in high-impedance state when low. |
Key Features
| Feature | Design Value |
|---|---|
| No start-up initialization | RF-modulated architecture eliminates boot sequence delays - outputs become valid immediately after UVLO exit (~0.3 ms). |
| Tri-state outputs with EN1/EN2 | Enables shared-bus topologies (e.g., isolated CAN or SPI buses) by allowing multiple isolators to coexist on same net without contention. |
| Selectable fail-safe mode | Ordering option defines default output state (high or low) during VDD loss - critical for safe shutdown in motor control and BMS. |
| High electromagnetic immunity | 100 kV/µs common-mode transient immunity ensures stable operation near IGBTs, SiC MOSFETs, and high-frequency switching nodes. |
| Reinforced IEC 60747-17 rating | Validated insulation structure supports end-equipment certification to IEC 62368-1 and IEC 60601-1 without additional system-level barriers. |
Applications
| Industrial Motor Control | Automotive Battery Management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM6603ARIZ-RL | 6-channel, 50 Mbps max, integrated isolated DC/DC converter; 3750 VRMS rating; no AEC-Q100 qualification. | Preferred where board space is constrained and isolated power is needed; unsuitable for 6000 VRMS or automotive qualification requirements. | Choose ADUM6603ARIZ-RL only if isolated bias supply is required and 6000 VRMS is not mandated. |
| ISO6763RQWR | 6-channel, 50 Mbps, 5000 VRMS, no AEC-Q100; uses capacitive isolation; lower CMTI (85 kV/µs); different pinout (SOIC-16 NB). | Acceptable for cost-sensitive industrial PLC I/O modules but lacks reinforced insulation certification for medical or automotive end-equipment. | Choose ISO6763RQWR only for non-safety-critical 2.5 kVRMS applications where footprint compatibility with narrow-body SOIC-16 is required. |
Compared with ADUM6603ARIZ-RL and ISO6763RQWR, SI86S663BB-AUR delivers higher speed (150 vs. 50 Mbps), certified 6000 VRMS reinforced isolation, and AEC-Q100 qualification - making it uniquely suitable for high-performance automotive traction inverters and industrial servo drives requiring functional safety and high noise immunity.

FAQ
What is the isolation voltage rating of the SI86S663BB-AUR?
The SI86S663BB-AUR is rated for 6000 VRMS isolation for 1 minute per UL 1577 and certified to IEC 60747-17 for reinforced insulation. This rating applies to the WB SOIC-16 package and is validated for continuous working voltage up to 1140 V peak in end-equipment complying with IEC 62368-1 and IEC 60601-1 standards.
Does the SI86S663BB-AUR require external startup initialization or configuration?
No, the SI86S663BB-AUR requires no startup initialization. Its RF-modulated architecture enables immediate channel operation after exiting undervoltage lockout (~0.3 ms). Outputs follow input states directly upon stabilization, with no firmware, register writes, or clock setup needed - unlike SPI-isolator variants such as Si86SS51.
What is the function of EN1 and EN2 pins on the SI86S663BB-AUR?
EN1 and EN2 are active-high enable inputs controlling tri-state behavior of all six channels on Side A and Side B respectively. When low, they place corresponding side's outputs in high-impedance state - essential for bus arbitration in multi-master isolated networks. Neither pin has internal pull-up; external biasing is required for defined default state.
Is the SI86S663BB-AUR qualified for automotive applications?
Yes, the SI86S663BB-AUR is AEC-Q100 qualified (Grade 0, –40 to +125 °C) and manufactured using automotive-specific process flows. It supports PPAP documentation, IMDS/CAMDS compliance, and is approved for use in onboard chargers, battery management systems, and traction inverters per AIAG requirements.
What are the supply voltage requirements for SI86S663BB-AUR operation?
The SI86S663BB-AUR operates with independent 2.25–5.5 V supplies on both sides (VDD1/GND1 and VDD2/GND2). Each side requires local 0.1 µF ceramic + 10 µF bulk bypass capacitors placed adjacent to the respective VDD/GND pins. Operation outside this range triggers undervoltage lockout, holding outputs in fail-safe state.
