Product details
Overview
SI86S660EE-AS2R from Skyworks Solutions is a 6-channel reinforced digital isolator with 6000 VRMS isolation, 150 Mbps data rate, and AEC-Q100 qualification for automotive systems. It features dual 2.25–5.5 V supplies, 10 ns typical propagation delay, and fail-safe default-low output mode - deployed in battery management systems and traction inverters where high-voltage signal integrity and functional safety are critical.
For engineers reviewing the SI86S660EE-AS2R datasheet, SI86S660EE-AS2R pinout, SI86S660EE-AS2R application, or SI86S660EE-AS2R equivalent, this page delivers verified specifications, validated pin functions, automotive-grade safety certifications (IEC 60747-17, UL 1577), and real-world use context for isolated SPI, motor control feedback, and HV/LV domain bridging.
Technical Context
The SI86S660EE-AS2R implements RF-based on/off keying across a semiconductor isolation barrier, eliminating startup initialization and enabling robust noise immunity (100 kV/µs CMTI). Its architecture supports independent UVLO and reset per side (VDD1/VDD2), with RSTB thresholds at ~1.7 V and UVLO hysteresis of 105–160 mV.
All six channels operate bidirectionally via Schmitt-trigger CMOS inputs and tri-state outputs controlled by EN1/EN2 pins. The device uses HF XMTR/RCVR circuitry per channel and supports fail-safe operation with default-low output state during unpowered conditions on either side.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 150 Mbps - enables high-speed isolated communication in motor control loops and fast ADC/DAC interfaces. |
| Isolation Rating | 6000 VRMS (1 min) - meets reinforced insulation requirements for 1000 VAC+ systems like onboard chargers and inverters. |
| Propagation Delay | 10 ns typical - ensures tight timing alignment between isolated control and feedback signals in closed-loop power stages. |
| Supply Voltage | 2.25–5.5 V per side - supports interoperability with 3.3 V and 5 V logic domains without level shifters. |
| Operating Temp | –40 to +125 °C - qualified for under-hood automotive environments and industrial motor drives. |
| CMTI | ≥100 kV/µs - rejects fast transients common in IGBT/SiC switching noise, preventing false triggering. |

Pinout & Package
SI86S660EE-AS2R is housed in a WB SOIC-16 package (wide-body, 10.3 mm creepage/clearance), supporting 6000 VRMS isolation. Pin assignments follow Figure 4 (Si86S660) in the datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Side A supply pair | Power and ground for input-side logic (A1–A6, EN1); bypass requires 0.1 µF + 10 µF capacitors. |
| A1–A6 | Digital I/O (Side A) | Unidirectional or bidirectional isolated data channels; Schmitt-trigger inputs with 0.15×VDD hysteresis. |
| EN1 | Active-high enable (Side A) | Tri-states all A-side outputs when low; used for synchronized shutdown in multi-isolator systems. |
| VDD2, GND2 | Side B supply pair | Independent power domain for output-side logic (B1–B6, EN2); enables galvanic separation of HV/LV domains. |
| B1–B6 | Digital I/O (Side B) | Corresponding isolated outputs/inputs; fail-safe default-low behavior active when VDD2 powered but VDD1 unpowered. |
| EN2 | Active-high enable (Side B) | Tri-states all B-side outputs; allows dynamic isolation of downstream peripherals without resetting the entire chain. |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation | Eliminates LED aging and temperature drift of optocouplers; no start-up initialization required. |
| Fail-safe default-low | Guarantees safe output state during power loss on Side A - critical for fault-tolerant gate drivers and BMS monitoring. |
| Tri-state outputs | EN1/EN2 pins provide hardware-controlled bus arbitration and hot-swap capability in modular systems. |
| High CMTI immunity | 100 kV/µs minimum transient immunity prevents corruption in noisy inverter environments with fast dV/dt edges. |
| Automotive qualification | AEC-Q100 Grade 0 (–40 to +125 °C), PPAP-ready, IMDS/CAMDS compliant - suitable for ASIL-B system integration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM6600ARIZ-RL | 6-channel, 6000 VRMS, 150 Mbps, but uses iCoupler® transformer technology and lacks AEC-Q100 qualification. | Targeted at industrial automation; not certified for automotive use or medical isolation standards. | Select ADUM6600ARIZ-RL only for non-automotive applications requiring same channel count and isolation rating without automotive traceability. |
| ISO6760FRDWR | 6-channel, 5000 VRMS, 50 Mbps max, TI's capacitive isolator with lower CMTI (85 kV/µs) and no AEC-Q100 grade. | Designed for cost-sensitive industrial PLCs; insufficient for 6000 VRMS or EV traction inverter requirements. | Choose ISO6760FRDWR only when budget constraints outweigh need for 150 Mbps speed, 6000 VRMS, or automotive qualification. |
Compared with ADUM6600ARIZ-RL and ISO6760FRDWR, SI86S660EE-AS2R uniquely combines AEC-Q100 Grade 0, 6000 VRMS, 150 Mbps, and 100 kV/µs CMTI - making it the only option qualified for safety-critical EV powertrain subsystems requiring full regulatory alignment.

FAQ
What is the isolation rating and certification status of SI86S660EE-AS2R?
SI86S660EE-AS2R provides 6000 VRMS isolation for 1 minute per UL 1577 and is certified to IEC 60747-17 (reinforced), CSA 62368-1/60601-1, and CQC GB4943.1. These approvals are documented in Skyworks' official safety reports and support system-level compliance in EV and medical applications. SI86S660EE-AS2R meets reinforced insulation requirements for 1000 VAC+ working voltages.
Does SI86S660EE-AS2R support fail-safe operation, and how is it configured?
Yes, SI86S660EE-AS2R is ordered with default-low fail-safe mode (denoted by "E" in the part number suffix). When VDD1 is unpowered but VDD2 remains active, all B-side outputs default to logic low - ensuring safe shutdown of downstream gate drivers or sensors. This behavior is hardwired per ordering option and does not require external configuration. SI86S660EE-AS2R implements this via internal UVLO and reset circuitry tied to RSTB (~1.7 V) thresholds.
What are the supply voltage requirements and bypassing recommendations for SI86S660EE-AS2R?
SI86S660EE-AS2R operates from 2.25 V to 5.5 V on both VDD1 and VDD2 sides independently. Each supply requires a 0.1 µF ceramic capacitor plus a 10 µF bulk capacitor placed adjacent to the respective VDD/GND pins. This dual-capacitor network suppresses high-frequency noise and sustains transient current demands during 150 Mbps data bursts. SI86S660EE-AS2R exhibits UVLO hysteresis of 105–160 mV to prevent oscillation near supply thresholds.
How does SI86S660EE-AS2R handle power sequencing and undervoltage conditions?
SI86S660EE-AS2R features independent UVLO and reset monitors on each side: VDDUV+ = 2.10–2.25 V and RSTB+ ≈ 1.7 V. During startup, outputs remain low for 0.3 ms until VDD stabilizes above UVLO+, then follow inputs or enter fail-safe state. If VDD drops below RSTB–, a full reset occurs and configuration reloads upon recovery. SI86S660EE-AS2R guarantees deterministic behavior even with asymmetric power sequencing between sides.
Is SI86S660EE-AS2R pin-compatible with other devices in the Si86S6xx family?
SI86S660EE-AS2R shares the same WB SOIC-16 pinout as Si86S661, Si86S662, and Si86S663 per Figure 4 of the datasheet - differing only in channel direction mapping and fail-safe default state (E = low, D = high). All variants use identical A1–A6/B1–B6, EN1/EN2, VDD1/VDD2, and GND1/GND2 assignments. SI86S660EE-AS2R can be substituted within the same footprint when default-low behavior and 6-channel count are required.
