Product details
Overview
SI86SM41EC-IS1 from Skyworks Solutions is a four-channel, reinforced digital isolator with sleep mode control (SMb pin), 6000 VRMS isolation rating, 150 Mbps data rate, and operation across –40 to 125 °C. It provides bidirectional signal isolation between microcontroller SPI peripherals and high-voltage motor control gate drivers in battery management systems.
For engineers reviewing the SI86SM41EC-IS1 datasheet, SI86SM41EC-IS1 pinout, SI86SM41EC-IS1 application, or SI86SM41EC-IS1 equivalent, this page delivers verified technical context, exact pin functions, fail-safe output behavior, sleep-mode power savings, and automotive-grade safety certifications including AEC-Q100 and IEC 60747-17.
Technical Context
The SI86SM41EC-IS1 implements RF-based on/off keying modulation across a semiconductor isolation barrier, eliminating startup initialization and enabling deterministic timing. Its architecture supports independent UVLO monitoring per side (VDD1/VDD2), RSTB reset thresholds (~1.7 V), and configurable default output state (high/low) during unpowered conditions.
Sleep mode is activated via the active-low SMb pin, reducing quiescent current to 750 µA per side while retaining one always-on channel for wake-up detection. All I/Os feature Schmitt-trigger + CMOS thresholds, 36 ns input deglitch filtering, and 100 kV/µs CMTI immunity - confirmed for Si86S64x-family variants including SI86SM41.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - supports high-speed SPI clocking up to 75 MHz with full-duplex timing margin. |
| Isolation rating | 6000 VRMS - meets reinforced insulation requirements per UL 1577 and IEC 60747-17 for industrial and automotive safety-critical systems. |
| Propagation delay | 10 ns typical - enables tight timing budgets in closed-loop motor control and isolated ADC sampling. |
| Supply voltage | 2.25–5.5 V - allows direct interface with 3.3 V and 5 V logic domains without level-shifting circuitry. |
| Operating temperature | –40 to 125 °C - qualified for under-hood automotive applications and industrial inverters. |
| CMTI immunity | ≥100 kV/µs - prevents false triggering in high-di/dt environments like traction inverters and SMPS. |
| Sleep current | 750 µA per side - reduces system standby power in battery-powered BMS and charging stations. |
Pinout & Package
SI86SM41EC-IS1 is housed in a WB SOIC-16 package (wide-body, 10.3 mm creepage/clearance) with reinforced insulation and RoHS-compliant finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Side A power supply | Supplies isolated controller-side logic; requires 0.1 µF + 10 µF bypass capacitors placed adjacent to pins. |
| A1–A4 | Side A digital I/O | Four bidirectional channels; Schmitt-trigger inputs tolerate slow-rising signals in noisy motor drive environments. |
| SMb | Sleep mode control | Active-low input: drives device into 750 µA/side sleep mode; open or high enables normal operation. |
| Isolation Barrier | Die-level separation | CMOS-based barrier providing 6000 VRMS withstand, 100 kV/µs CMTI, and 60-year lifetime per IEC 60747-17. |
| B1–B4 | Side B digital I/O | Four isolated output channels; tri-state capable via EN1/EN2 (not present on SI86SM41 - uses SMb only). |
| VDD2, GND2 | Side B power supply | Independent 2.25–5.5 V supply for high-voltage domain; UVLO+ = 2.18 V ensures robust start-up. |
Key Features
| Feature | Design Value |
|---|---|
| Sleep mode control | SMb pin reduces total quiescent current to 1.5 mA (750 µA per side) without sacrificing wake-up latency or timing performance. |
| Fail-safe output selection | Ordering option sets default output state to logic high or low during VDD1 undervoltage, preventing undefined gate driver states in BMS fault conditions. |
| Input noise filtering | 36 ns deglitch time rejects sub-36 ns transients from switching noise in motor control and SMPS circuits. |
| Reinforced safety certification | UL 1577, VDE 60747-17, CSA 62368-1, and CQC GB4943.1 approvals enable single-component compliance for medical and EV systems. |
| RF modulation architecture | No start-up initialization required; eliminates boot-time uncertainty in real-time control loops and safety shutdown paths. |

FAQ
What is the isolation voltage rating of SI86SM41EC-IS1 and which safety standards does it meet?
SI86SM41EC-IS1 has a 6000 VRMS isolation rating per UL 1577 for 1 minute and is certified to IEC 60747-17 (reinforced insulation), CSA 62368-1, VDE 62368-1, and CQC GB4943.1. These approvals validate its use in medical, automotive, and industrial equipment requiring reinforced insulation barriers. The wide-body SOIC-16 package ensures 10.3 mm creepage distance for 800 V DC systems.
Does SI86SM41EC-IS1 support fail-safe output configuration, and how is it implemented?
Yes, SI86SM41EC-IS1 offers ordering options for default high- or low-output states during VDD1 undervoltage conditions. This fail-safe behavior is factory-set and ensures predictable gate driver or ADC interface states during brownout events in battery management systems. The setting is fixed per part number and cannot be changed in-circuit.
How does the SMb pin function in SI86SM41EC-IS1, and what is its impact on power consumption?
The SMb pin is an active-low sleep mode control input. When driven low, SI86SM41EC-IS1 enters sleep mode with 750 µA quiescent current per side (1.5 mA total), while retaining one always-on channel to monitor SMb for wake-up. This reduces standby power by >90% versus active operation, critical for energy-sensitive EV charging and BMS applications.
What is the propagation delay and pulse width distortion specification for SI86SM41EC-IS1?
SI86SM41EC-IS1 has a typical propagation delay of 10 ns and pulse width distortion of 3.5 ns, measured at VDD = 5 V and TA = 25 °C. These values are guaranteed over the full –40 to 125 °C operating range and enable precise timing alignment in high-speed SPI interfaces and real-time motor control feedback loops.
Is SI86SM41EC-IS1 qualified for automotive applications, and what documentation is available?
Yes, SI86SM41EC-IS1 is AEC-Q100 qualified (Grade 0, –40 to 125 °C) and supported with AIAG-compliant PPAP documentation, IMDS/CAMDS listings, and automotive-specific manufacturing flow validation. Skyworks provides full automotive-grade reliability data, including HTOL, TC, and UHAST reports upon request for SI86SM41EC-IS1.
