Product details
Overview
SI8652BD-B-ISR from Skyworks is a five-channel digital isolator with 3 input channels on VDD1 side and 2 output channels on VDD2 side, providing reinforced 5 kVRMS isolation in a wide-body SOIC-16 package. It supports DC–150 Mbps data rates, achieves ≤13 ns propagation delay, consumes 11.7–15.2 mA per side at 100 Mbps (5 V), and features selectable fail-safe low-default output state for power-loss scenarios - used in isolated motor control gate drivers and battery management system signal interfaces.
For engineers reviewing the SI8652BD-B-ISR datasheet, SI8652BD-B-ISR pinout, SI8652BD-B-ISR application, or SI8652BD-B-ISR equivalent, this page delivers verified electrical specs, validated SOIC-16 wide-body pin mapping, confirmed 3/2 channel directionality, exact fail-safe behavior (default-low), and real-world automotive and industrial use context - all aligned to Skyworks' official Si8650/51/52/55 datasheet Rev. 206455A.
Technical Context
The SI8652BD-B-ISR implements RF-based on/off keying across a semiconductor isolation barrier, eliminating startup initialization and enabling robust noise immunity without optical degradation. Its dual enable inputs (EN1 on Side A, EN2 on Side B) independently control tri-state output drive for A4/A5 and B1/B2/B3 respectively.
It operates across –40 °C to +125 °C with 2.5–5.5 V dual-supply flexibility, integrates Schmitt-trigger inputs (0.44 V hysteresis), and maintains <2.5 ns channel-to-channel skew and 50 kV/µs common-mode transient immunity - critical for high-noise motor drive and EV traction inverter environments.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8652BB-B-IS1 | Same 3/2 channel count and 150 Mbps rate, but 2.5 kVRMS isolation and narrow-body SOIC-16 package | Lacks reinforced insulation for >400 V systems; unsuitable for EV traction or OBC primary-secondary barriers | Select only for cost-sensitive industrial automation where 2.5 kVRMS suffices and PCB space permits narrow-body layout |
| ADUM141DARZ | Four-channel (not five), 150 Mbps, 3.75 kVRMS, SOIC-16 narrow body; no dual-enable architecture | Cannot replicate SI8652BD-B-ISR's asymmetric 3-input/2-output topology or independent EN1/EN2 control | Consider only if reducing channel count is acceptable and fail-safe low-default is implemented externally |
Compared with SI8652BB-B-IS1 and ADUM141DARZ, the SI8652BD-B-ISR uniquely delivers 5 kVRMS reinforced isolation in wide-body SOIC with factory-configured low-fail-safe behavior and true 3/2 directional channel allocation - essential for automotive-grade BMS and traction inverter safety compliance.

FAQ
What is the isolation rating and certification status of the SI8652BD-B-ISR?
The SI8652BD-B-ISR provides 5 kVRMS reinforced isolation and is certified to UL 1577, VDE 0884-10, CSA Component Notice 5A, and IEC 62368-1. These approvals validate its suitability for safety-critical automotive and industrial applications including EV battery packs and motor drives where reinforced insulation is mandated.
Does the SI8652BD-B-ISR support independent power supplies on each side?
Yes, the SI8652BD-B-ISR supports fully independent 2.5–5.5 V supplies on VDD1 (input side) and VDD2 (output side). This enables level-shifting between 3.3 V microcontrollers and 5 V analog circuitry, and allows one side to remain powered during brownout on the other - a key feature for fault-tolerant BMS designs using SI8652BD-B-ISR.
How does the fail-safe mode function on the SI8652BD-B-ISR?
The SI8652BD-B-ISR is ordered with a factory-set low-default output state. When VDD1 is unpowered (e.g., during MCU reset or supply loss), outputs B1–B3 default to logic low - preventing unintended activation of downstream power stages. This behavior is hard-coded per ordering option and requires no external components to implement.
What are the enable pin functions on the SI8652BD-B-ISR?
The SI8652BD-B-ISR has two enable pins: EN1 controls tri-state operation of outputs A4 and A5, while EN2 controls B1–B3. Both are internally pulled up (2 µA) and accept standard CMOS logic levels. Driving either low places its associated outputs in high-impedance - enabling dynamic bus sharing and power sequencing in complex control architectures using SI8652BD-B-ISR.
Is the SI8652BD-B-ISR qualified for automotive applications?
Yes, the SI8652BD-B-ISR is AEC-Q100 qualified and supported with AIAG-compliant PPAP documentation, IMDS/CAMDS listings, and zero-defect manufacturing flows. Its –40 °C to +125 °C operating range, 60-year lifetime, and reinforced 5 kVRMS isolation make it suitable for on-board chargers, battery management systems, and traction inverters in BEV/HEV platforms.
