Product details
Overview
SI86SL42EE-AS2R 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 two forward and two reverse isolated channels, Schmitt-trigger inputs, tri-state outputs with enable, and operates across –40 to 125 °C in a WB SOIC-16 package. Used in battery management systems and traction inverters where high noise immunity and fail-safe operation are critical.
For engineers reviewing the SI86SL42EE-AS2R datasheet, SI86SL42EE-AS2R pinout, SI86SL42EE-AS2R application, or SI86SL42EE-AS2R equivalent, key selection criteria include reinforced IEC 60747-17 rating, 10 ns typical propagation delay, 3.5 ns pulse width distortion, sleep mode support via SMb pin, and default-low fail-safe output configuration.
Technical Context
The SI86SL42EE-AS2R implements RF-based on/off keying across a semiconductor isolation barrier, eliminating startup initialization and enabling robust noise immunity. Its architecture supports bidirectional signal flow with independent side-A and side-B power domains (2.25–5.5 V), each with dedicated UVLO and reset circuitry (RSTB– ~1.7 V).
It integrates a dedicated SMb pin for active-low sleep mode control, reducing quiescent current to 750 µA per side while retaining one always-on channel to monitor SMb state. The device uses CMOS thresholds and Schmitt-trigger inputs to ensure reliable operation in high-CMTI environments (>100 kV/µs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - supports high-speed serial interfaces including SPI and isolated ADC/DAC links. |
| Isolation rating | 6000 VRMS - meets reinforced insulation requirements per UL 1577 and IEC 60747-17 for safety-critical automotive and industrial systems. |
| Propagation delay | 10 ns typical - enables precise timing alignment in motor control gate drivers and real-time feedback loops. |
| Pulse width distortion | 3.5 ns typical - preserves duty cycle integrity for PWM and clock distribution across isolation barrier. |

| Fail-safe mode | Default low output - ensures safe shutdown state during power loss on input side while output side remains powered. |
Pinout & Package
SI86SL42EE-AS2R is housed in a wide-body SOIC-16 (WB SOIC-16) package with creepage/clearance compliant for 6000 VRMS working voltage. Pin assignments follow the Si86SM42 layout (Figure 3), supporting two forward (A→B) and two reverse (B→A) channels plus SMb control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM141D1BRZ | 4-channel, 150 Mbps, 3750 VRMS isolation, no sleep mode, 2.5–5.5 V supply | Lacks AEC-Q100 qualification and 6000 VRMS rating; limited to non-automotive industrial use | Select when cost sensitivity outweighs reinforced isolation and automotive compliance requirements. |

FAQ
What is the isolation rating and safety certification status of SI86SL42EE-AS2R?
SI86SL42EE-AS2R provides 6000 VRMS reinforced isolation per UL 1577 and is certified to IEC 60747-17. It also meets CSA 62368-1 and 60601-1, and CQC GB4943.1 standards. These certifications are fully documented for SI86SL42EE-AS2R and validated for automotive-grade use cases including battery management and traction inverters.
Does SI86SL42EE-AS2R support fail-safe output behavior during power loss?
Yes, SI86SL42EE-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, outputs B1–B4 are held low-ensuring safe shutdown of downstream gate drivers or control logic in SI86SL42EE-AS2R-based systems.
How does the SMb pin function in SI86SL42EE-AS2R, and what power savings does it enable?
The SMb pin is an active-low sleep mode control. When driven low, SI86SL42EE-AS2R enters sleep mode drawing just 750 µA per side while retaining one always-on channel to detect SMb release. This reduces quiescent current by >70% versus normal operation, extending standby time in battery-powered automotive ECUs using SI86SL42EE-AS2R.
What are the key timing specifications of SI86SL42EE-AS2R relevant for motor control applications?
SI86SL42EE-AS2R delivers 10 ns typical propagation delay and 3.5 ns typical pulse width distortion-critical for matched PWM channel timing in three-phase inverter gate drivers. These values are measured at 5 V supply and –40 to 125 °C, ensuring consistent performance across SI86SL42EE-AS2R's full automotive operating range.
Is SI86SL42EE-AS2R compatible with standard SOIC-16 PCB footprints, and what package variant does it use?
SI86SL42EE-AS2R uses the WB SOIC-16 (wide-body SOIC-16) package with 7.5 mm creepage, distinct from standard 3.9 mm SOIC-16. It requires specific land patterns per Skyworks' AN1359 layout guidelines to maintain 6000 VRMS isolation integrity and thermal performance in SI86SL42EE-AS2R implementations.
