Product details
Overview
SI86SL41EE-IS2R from Skyworks Solutions is a 4-channel, low-power digital isolator with reinforced 6000 VRMS isolation, 150 Mbps data rate, and AEC-Q100 qualification for automotive systems. It features Schmitt-trigger inputs, tri-state outputs with enable, selectable fail-safe default (high/low), and operates across –40 to 125 °C in NB SOIC-16 package. It is used in battery management systems and isolated ADC interfaces where high noise immunity and supply voltage flexibility (2.25–5.5 V) are critical.
For engineers reviewing the SI86SL41EE-IS2R datasheet, SI86SL41EE-IS2R pinout, SI86SL41EE-IS2R application, or SI86SL41EE-IS2R equivalent, this page delivers verified specifications, functional context, real-world use cases, and validated alternative options - all aligned to Skyworks' official Si86S6xx/Lxx family documentation dated August 17, 2023.
Technical Context
The SI86SL41EE-IS2R 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 bidirectional signal transfer across four independent channels with side-specific enable control (EN1/EN2) and failsafe output state selection during unpowered conditions.
It integrates undervoltage lockout (UVLO+ = 2.18 V, UVLO– = 2.05 V) and reset circuitry (RSTB– ≈ 1.7 V) on both sides, ensuring deterministic behavior during power sequencing. The device uses CMOS thresholds with 0.15 × VDD input hysteresis and delivers typical 10 ns propagation delay with 3.5 ns pulse width distortion at 5 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - supports high-speed SPI, isolated ADC/DAC, and motor control feedback loops without timing bottlenecks. |
| Isolation rating | 6000 VRMS (1 min) - meets reinforced insulation requirements per UL 1577 and IEC 60747-17 for safety-critical automotive and industrial applications. |
| Propagation delay | 10 ns (typical) - enables precise timing alignment in closed-loop control systems such as traction inverters and onboard chargers. |
| Supply voltage | 2.25–5.5 V - allows direct interface with 3.3 V and 5 V logic domains without level-shifting components. |
| Operating temperature | –40 to 125 °C - qualified for under-hood automotive environments and industrial automation enclosures. |
| CMTI | ≥100 kV/µs - ensures reliable operation in high dv/dt noise environments like power inverters and motor drives. |
| Fail-safe mode | Selectable default high/low output - prevents undefined states during brownout or power-loss events in BMS and safety monitoring circuits. |
Pinout & Package
NB SOIC-16 package (narrow-body, 150 mil width), RoHS-compliant, with creepage/clearance optimized for reinforced insulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Side A power supply | Provides isolated power domain for primary-side logic (e.g., MCU SPI controller); requires 0.1 µF + 10 µF bypass capacitors. |
| VDD2, GND2 | Side B power supply | Supplies secondary-side circuitry (e.g., isolated ADC, gate driver); independent of Side A for true galvanic separation. |
| A1–A4 | Side A digital I/O | Four unidirectional input channels from controller side; compatible with CMOS/Schmitt-trigger logic levels. |
| B1–B4 | Side B digital I/O | Four corresponding isolated output channels to peripheral side; tri-state capable via EN2 control. |
| EN1, EN2 | Active-high enable | Controls output drivers on respective side; enables single-point shutdown for power gating or fault isolation. |
| NC | No connect | Pins 7 and 15 are internally unused - must remain unconnected per datasheet Figure 2 (Si86S64x/L4x pinout). |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation | Eliminates LED aging and temperature drift issues of optocouplers; no start-up initialization required for deterministic boot behavior. |
| Sleep mode support | Reduces quiescent current by >75% vs. standard Si86S6x variants - critical for always-on BMS monitoring circuits. |
| Input deglitch filter | 36 ns filtering (on Si86S64x variants) rejects sub-36 ns noise pulses - improves reliability in EMI-heavy motor drive environments. |
| Tri-state outputs | EN1/EN2 pins allow bus sharing across multiple isolated peripherals without contention - simplifies multi-device SPI isolation. |
| AEC-Q100 Grade 1 | Validated for automotive applications including traction inverters and onboard chargers - includes PPAP documentation and IMDS support. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM140D0BRIZ | 4-channel, 150 Mbps, 3750 VRMS isolation; 2.7–5.5 V supply; no AEC-Q100 qualification. | Targeted at industrial automation, not automotive-grade systems requiring PPAP or IMDS documentation. | Choose when cost sensitivity outweighs automotive qualification needs and 3750 VRMS suffices for system-level safety design. |
| ISO6741FDWR | 4-channel, 50 Mbps, 5000 VRMS; 1.71–5.5 V supply; AEC-Q100 Grade 1; integrated LDO on isolated side. | Lower data rate limits use in high-speed SPI or fast ADC interfaces; LDO simplifies secondary-side power design. | Prefer when secondary-side power regulation is needed and 50 Mbps meets timing requirements - reduces external BOM count. |

FAQ
What is the isolation voltage rating of the SI86SL41EE-IS2R?
The SI86SL41EE-IS2R is rated for 6000 VRMS isolation for one minute per UL 1577 and certified to IEC 60747-17 for reinforced insulation. This rating applies to its NB SOIC-16 package and is validated for continuous operation in automotive and industrial environments up to 125 °C ambient temperature.
Does the SI86SL41EE-IS2R support fail-safe output configuration?
Yes, the SI86SL41EE-IS2R offers a selectable fail-safe mode where the output defaults to either high or low during input-side power loss - determined by ordering option suffix. This behavior is confirmed in Table 4 of the datasheet and ensures predictable state handling in BMS and safety-critical monitoring circuits.
What are the supply voltage requirements for SI86SL41EE-IS2R operation?
The SI86SL41EE-IS2R operates with independent 2.25–5.5 V supplies on both sides (VDD1 and VDD2). Each side requires local 0.1 µF and 10 µF bypass capacitors. The device maintains full functionality across this range, enabling interoperability with 3.3 V and 5 V logic families without level shifters.
How does the SI86SL41EE-IS2R achieve high noise immunity?
The SI86SL41EE-IS2R achieves ≥100 kV/µs common-mode transient immunity (CMTI) through its RF-based on/off keying architecture and Schmitt-trigger inputs with 0.15 × VDD hysteresis. These features suppress fast transients from power switches and motor drives without requiring external filtering components.
Is the SI86SL41EE-IS2R pin-compatible with other Si86S6xx family members?
Yes, the SI86SL41EE-IS2R shares the same NB SOIC-16 pinout as Si86S640/641/642 and Si86L40/L41/L42 variants per Figure 2 of the datasheet. Pin functions (A1–A4, B1–B4, EN1, EN2, VDD1/GND1, VDD2/GND2) are identical - enabling drop-in replacement within the same channel count and directionality configuration.
