Product details
Overview
SI8622ED-ASR from Skyworks Solutions is a dual-channel, reinforced-isolation digital isolator in WB SOIC-16 package, supporting up to 150 Mbps data rate, <10 ns propagation delay, and 5 kVRMS isolation rating. It features Schmitt-trigger inputs, selectable fail-safe output (default low), and operates from 2.5–5.5 V on both sides - used in battery management systems and traction inverters where high CMTI (>50 kV/µs) and automotive-grade reliability are required.
For engineers reviewing the SI8622ED-ASR datasheet, SI8622ED-ASR pinout, SI8622ED-ASR application, or SI8622ED-ASR equivalent, this page delivers verified specifications, validated WB SOIC-16 pin mapping, real-world automotive and industrial use cases, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The SI8622ED-ASR implements RF-based on/off keying across a semiconductor isolation barrier, eliminating startup initialization and enabling robust noise immunity without optical degradation. Its dual-channel architecture supports independent side-A and side-B power domains (VDD1/VDD2), each with dedicated undervoltage lockout (UVLO+ = 2.24 V, UVLO– = 2.16 V) and fail-safe control logic.
It delivers precise timing performance: 0.5 ns typical channel-channel skew, 2 ns propagation delay skew, and 5 ns minimum pulse width - critical for synchronized gate driving in isolated DC-DC converters and motor control feedback loops. Reinforced insulation per VDE 0884-10 and 5 kVRMS working voltage enable compliance in safety-critical automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | Up to 150 Mbps - supports high-speed SPI, RS-485, and CAN FD signal isolation without timing bottlenecks. |
| Propagation delay | 5.0–14 ns - ensures sub-15 ns end-to-end latency for real-time control loop closure in inverters. |
| Isolation rating | 5 kVRMS reinforced - certified to VDE 0884-10 and UL 1577, enabling direct integration into 400–800 V EV battery domains. |
| Supply voltage | 2.5–5.5 V per side - allows interoperability with 3.3 V microcontrollers and 5 V analog front-ends without level shifters. |
| CMTI | ≥50 kV/µs - suppresses false triggering during fast dv/dt transients in SiC/GaN power stages. |
| Fail-safe mode | Default low output - ensures safe shutdown of downstream drivers when VDD1 is unpowered (e.g., MCU reset). |
| Operating temperature | –40 to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive applications. |
Pinout & Package
SI8622ED-ASR uses a wide-body SOIC-16 (WB SOIC-16) package with 8.3 mm creepage/clearance, optimized for reinforced insulation in high-voltage systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND1 (Pins 1, 7) | Side 1 ground reference | Return path for VDD1 domain; must be star-connected to minimize ground bounce in isolated logic interfaces. |
| VDD1 (Pin 3) | Side 1 supply input | Power for input-side circuitry (A1, A2); requires 0.1 µF bypass capacitor placed adjacent to pin. |
| A1 (Pin 4), A2 (Pin 5) | Side 1 digital I/O | Input channels accepting 2.0 V VIH / 0.8 V VIL; Schmitt-triggered for >0.4 V hysteresis against EMI. |
| GND2 (Pins 9, 16) | Side 2 ground reference | Isolated return for VDD2 domain; physically separated from GND1 to maintain creepage integrity. |
| VDD2 (Pin 14) | Side 2 supply input | Power for output-side circuitry (B1, B2); independent of VDD1 - enables level-shifting between domains. |
| B1 (Pin 13), B2 (Pin 12) | Side 2 digital I/O | Output channels with 50 Ω nominal impedance; designed for controlled-impedance PCB traces to prevent reflections at 100+ Mbps. |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation architecture | Eliminates LED aging and temperature drift; achieves stable timing over –40 to +125 °C with no calibration. |
| Selectably fail-safe output | Factory-configured default-low state prevents unintended activation of power stage drivers during MCU boot or brownout. |
| Ultra-low power at 1 Mbps | 3.4 mA (VDD1) + 4.2 mA (VDD2) at 2.5 V - reduces thermal load in sealed battery enclosures. |
| High CMTI immunity | ≥50 kV/µs common-mode transient rejection - maintains data integrity during 1000 V/µs switching events in SiC inverters. |
| AEC-Q100 qualified | Grade 1 qualification confirms suitability for automotive powertrain systems including onboard chargers and traction inverters. |
Applications
| Battery Management System (BMS) | Traction Inverter Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM220N1BRZ | 2.5 kVRMS basic isolation; SOIC-8 package; 150 Mbps; default-high fail-safe. | Limited to industrial non-automotive use due to lower isolation rating and lack of AEC-Q100 qualification. | Choose when cost-sensitive industrial designs require smaller footprint and basic isolation suffices. |
| ISO7721DWR | 5 kVRMS reinforced isolation; SOIC-8; 100 Mbps; no selectable fail-safe (fixed default-low). | Valid for automotive BMS but lacks RF-based jitter performance: 100 Mbps max vs. SI8622ED-ASR's 150 Mbps. | Prefer when board space is constrained and 100 Mbps bandwidth meets system requirements. |
Compared with ADUM220N1BRZ and ISO7721DWR, SI8622ED-ASR uniquely combines AEC-Q100 Grade 1 qualification, 150 Mbps speed, and factory-configurable fail-safe mode in a WB SOIC-16 package - making it the only option qualified for high-speed, safety-critical EV traction inverter gate drive.

FAQ
What is the isolation rating and safety certification of the SI8622ED-ASR?
The SI8622ED-ASR provides 5 kVRMS reinforced isolation and is certified to UL 1577, VDE 0884-10 (reinforced), CSA IEC 62368-1, and CQC GB4943.1. These approvals validate its use in automotive battery systems and industrial equipment requiring double insulation barriers.
Does the SI8622ED-ASR require external components for stable operation?
Yes - the SI8622ED-ASR requires a 0.1 µF ceramic bypass capacitor between VDD1 and GND1, and another between VDD2 and GND2, placed as close as possible to the pins. No pull-up/pull-down resistors are needed, as Schmitt-trigger inputs and internal fail-safe logic eliminate external biasing.
What is the meaning of "ED" and "ASR" in SI8622ED-ASR?
"ED" denotes the device variant with default-low fail-safe output configuration; "ASR" indicates automotive-grade qualification (AEC-Q100 Grade 1), wide-body SOIC-16 packaging, and tape-and-reel delivery. This exact ordering code maps to VDE-reinforced, 5 kVRMS, dual-channel functionality.
Can the SI8622ED-ASR operate with different supply voltages on each side?
Yes - SI8622ED-ASR supports independent 2.5–5.5 V supplies on VDD1 and VDD2, enabling seamless level translation between 3.3 V microcontrollers and 5 V gate drivers without external level shifters or shared ground references.
How does the SI8622ED-ASR handle power loss on the input side?
When VDD1 is unpowered while VDD2 remains active, SI8622ED-ASR drives both B1 and B2 outputs low (fail-safe default-low mode). This behavior is hardwired per the "ED" variant and prevents hazardous activation of downstream power devices during MCU brownout or reset sequences.
