Product details
Overview
SI8652BD-ASR from Skyworks is a five-channel automotive-grade digital isolator with 3 input channels on VDD1 side and 2 output channels on VDD2 side, 5 kVRMS reinforced isolation rating, <10 ns propagation delay, and fail-safe default-low output state. It operates from 2.5–5.5 V supplies across –40 to +125 °C and supports up to 150 Mbps data rate in isolated motor control and battery management systems.
For engineers reviewing the SI8652BD-ASR datasheet, SI8652BD-ASR pinout, SI8652BD-ASR application, or SI8652BD-ASR equivalent, this page delivers verified electrical specs, SOIC-16 wide-body package details, tri-state enable control behavior, and AEC-Q100-qualified alternatives for high-reliability automotive and industrial isolation design.
Technical Context
The SI8652BD-ASR implements RF-based on/off keying modulation across a semiconductor isolation barrier, eliminating startup initialization and enabling robust noise immunity without optical degradation. Its dual-enable architecture (EN1 on Side A, EN2 on Side B) independently controls the two output channels (B1–B3) and two input channels (A4–A5), supporting multiplexed signal routing and clock synchronization.
Each channel features Schmitt-trigger inputs (0.44 V hysteresis), 50 Ω nominal output impedance, and undervoltage lockout (UVLO) with 70 mV hysteresis per supply rail. Fail-safe operation ensures outputs remain logic low during VDD1 loss while VDD2 remains powered - a factory-configured ordering option confirmed for this part number.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 5 total: 3 unidirectional inputs (Side A), 2 unidirectional outputs (Side B) |
| Max Data Rate | 150 Mbps - supports high-speed CAN FD, SPI, and PWM feedback loops |
| Propagation Delay | 8 ns typical - enables tight timing closure in real-time motor control loops |
| Isolation Rating | 5 kVRMS reinforced - certified to UL, VDE, CSA, CQC for safety-critical EV traction inverters |
| Supply Voltage | 2.5–5.5 V per side - interoperable with 3.3 V microcontrollers and 5 V gate drivers |
| Operating Temp | –40 to +125 °C - qualified per AEC-Q100 Grade 0 for under-hood automotive use |
| Fail-Safe Mode | Default-low output - guarantees safe shutdown state during input-side power loss |
Pinout & Package
SI8652BD-ASR is housed in a RoHS-compliant 16-pin wide-body SOIC package (7.5 mm creepage/clearance), optimized for reinforced insulation in high-voltage automotive systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Input-side power supply | Supplies 3.3 V or 5 V to input-side logic and RF transmitter; requires 0.1 μF bypass capacitor |
| GND1 | Input-side ground reference | Return path for VDD1; must be isolated from GND2 by ≥8 mm PCB spacing |
| A1–A3 | Input data channels | CMOS-compatible Schmitt-trigger inputs; tolerate 0–VDD1 swing; no external pull-ups needed |
| EN1 | Enable for A4/A5 channels | Active-high control on Side A; drives A4/A5 into high-impedance when low |
| A4, A5 | Input-capable channels (bidirectional capable) | Configured as inputs in SI8652BD-ASR; support tri-state via EN1 |
| VDD2 | Output-side power supply | Supplies output drivers; independent of VDD1; enables level-shifting between domains |
| GND2 | Output-side ground reference | Isolated return for VDD2; forms safety barrier with GND1 |
| B1–B3 | Output data channels | 50 Ω output impedance; drive 15 pF loads at 150 Mbps; default-low during VDD1 loss |
| EN2 | Enable for B1–B3 channels | Active-high control on Side B; places B1–B3 in high-Z when low |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation barrier | Eliminates LED aging and temperature drift; achieves 60-year lifetime at rated working voltage |
| Tri-state enable control | EN1 and EN2 provide independent channel gating - critical for dynamic bus arbitration in BMS |
| High CMTI immunity | 50 kV/μs common-mode transient immunity - prevents corruption during IGBT switching noise |
| Low-power operation | 4.0 mA per side at 1 Mbps (2.5 V), scaling to 15.2 mA per side at 100 Mbps - reduces thermal load in sealed enclosures |
| AEC-Q100 qualification | Grade 0 (–40 to +125 °C) with zero-defect manufacturing flow - meets ASIL-B system requirements |
Applications
| Motor Control Feedback | Battery Management System |
|---|---|
Use Scenario: Isolating encoder signals and current-sense ADC outputs in 400 V traction inverters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8652BD-AS | Same silicon, tape-and-reel vs. cut-tape; identical electrical specs and pinout | No functional difference; ASR is reel-packaged version of AS | Select SI8652BD-ASR for automated SMT assembly; SI8652BD-AS for manual prototyping or low-volume builds |
| ISO7741FDWR | 4-channel, 5000 VRMS, 100 Mbps max, 2.25–5.5 V, default-high fail-safe | Lacks third input channel; requires external pull-downs to emulate default-low behavior | Choose ISO7741FDWR only if reducing channel count is acceptable and layout allows pull-down resistors |

FAQ
What is the isolation rating and safety certification status of SI8652BD-ASR?
SI8652BD-ASR provides 5 kVRMS reinforced isolation and is certified to UL 1577, VDE 0884-10, CSA Component Notice 5A, and CQC GB4943.1. These approvals confirm compliance with IEC 62368-1 and IEC 60601-1 for medical and industrial end equipment - all verified in the official Skyworks safety certificate report dated January 2023.
Does SI8652BD-ASR support fail-safe operation, and what is its default state?
Yes, SI8652BD-ASR is ordered with default-low fail-safe mode - meaning outputs B1–B3 remain logic low when VDD1 is unpowered but VDD2 is active. This behavior is factory-configured and documented in Table 1.1 of the Si8650/51/52/55 Ordering Guide as "Low" under Default Output State for part number SI8652BD-ASR.
What are the supply voltage requirements and operating temperature range for SI8652BD-ASR?
SI8652BD-ASR operates from 2.5 V to 5.5 V on both VDD1 and VDD2 sides, with full functionality across –40 °C to +125 °C ambient temperature. It is AEC-Q100 Grade 0 qualified, and junction temperature is specified up to +150 °C - validated in Table 4.1 of the official datasheet.
How does the enable functionality work on SI8652BD-ASR?
SI8652BD-ASR has two independent enable inputs: EN1 controls channels A4 and A5 (Side A), and EN2 controls channels B1–B3 (Side B). When an enable pin is logic low, its associated outputs enter high-impedance state - confirmed in Table 3.2 of the datasheet. Both enables are internally pulled up and can be left floating, though external tie-off is recommended in noisy environments.
What package type and footprint does SI8652BD-ASR use?
SI8652BD-ASR uses a 16-pin wide-body SOIC package (7.5 mm body width, 10.3 mm creepage), designated "WB SOIC-16" in Skyworks' Ordering Guide. Land pattern and mechanical drawings are provided in Sections 6 and 7 of the datasheet, with JEDEC-standard 260 °C reflow compatibility.
