Product details
Overview
SI8652BC-AS1R from Skyworks is a five-channel digital isolator with 3 input channels on VDD1 side and 2 output channels on VDD2 side, providing reinforced galvanic isolation up to 3.75 kVRMS in a narrow-body SOIC-16 package. It supports DC–150 Mbps data rates, achieves ≤13 ns propagation delay, and operates across –40°C to +125°C for industrial and automotive systems requiring high noise immunity and fail-safe operation.
For engineers reviewing the SI8652BC-AS1R datasheet, SI8652BC-AS1R pinout, SI8652BC-AS1R application, or SI8652BC-AS1R equivalent, this page delivers verified specifications, validated pin functions, confirmed automotive-grade AEC-Q100 qualification, and real-world use cases in battery management and motor control where precise timing, low power, and robust CMTI (>50 kV/µs) are critical selection criteria.
Technical Context
The SI8652BC-AS1R implements RF-based on/off keying modulation across a semiconductor isolation barrier, eliminating startup initialization and enabling immediate signal transmission upon power-up. Its dual enable inputs (EN1 on Side A, EN2 on Side B) independently control tri-state output behavior for A4/A5 and B1/B2/B3 respectively.
It features Schmitt-trigger inputs with 0.44 V typical hysteresis, 50 Ω nominal output impedance, and selectable fail-safe mode (default-low output state per ordering code). Undervoltage lockout (UVLO) operates independently on both sides with 70 mV typical hysteresis and 2.24 V rising threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 5 total: 3 inputs on VDD1 side, 2 outputs on VDD2 side - enables asymmetric signal routing in isolated feedback loops. |
| Max Data Rate | 150 Mbps - supports high-speed serial interfaces like SPI clock lines and isolated ADC/DAC data streams. |
| Propagation Delay | ≤13 ns max - ensures sub-ns timing alignment critical for closed-loop motor control and power converter gate drive synchronization. |
| Isolation Rating | 3.75 kVRMS - meets reinforced insulation requirements per IEC 62368-1 and UL 1577 for industrial safety-critical systems. |
| Supply Voltage | 2.5–5.5 V on both sides - allows interoperability with 3.3 V microcontrollers and 5 V analog front-ends without level shifters. |
| CMTI | ≥50 kV/µs - rejects fast common-mode transients in motor drives and inverters without data corruption. |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive applications including battery management systems. |
Pinout & Package
SI8652BC-AS1R is housed in a RoHS-compliant narrow-body SOIC-16 package (5.3 mm width), with creepage/clearance compliant to IEC 60950-1 and reinforced insulation standards. The package supports JEDEC J-STD-020 moisture sensitivity level 3 and peak reflow at 260°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Input-side power supply | Supplies 2.5–5.5 V to transmitter side; bypass capacitor required between VDD1 and GND1. |
| GND1 | Input-side ground reference | Reference for all Side A signals; must be separated from GND2 by ≥8 mm creepage for 3.75 kVRMS rating. |
| INA1–INA3 | Input channels (Side A) | Accept logic-level signals with Schmitt-trigger inputs; support 500 kHz–150 MHz square wave inputs. |
| EN1 | Enable for Side A outputs (A4, A5) | Drives A4/A5 into high-impedance when low; internally pulled up to VDD1 via 2 µA current source. |
| VDD2 | Output-side power supply | Supplies 2.5–5.5 V to receiver side; independent of VDD1 for true galvanic isolation. |
| GND2 | Output-side ground reference | Reference for all Side B signals; physically isolated from GND1 to maintain 3.75 kVRMS withstand voltage. |
| OUTB1–OUTB3 | Output channels (Side B) | Drive 50 Ω loads with VOH ≥ VDD2–0.4 V and VOL ≤ 0.4 V at 4 mA sink/source. |
| EN2 | Enable for Side B outputs (B1–B3) | Drives B1–B3 into high-impedance when low; internally pulled up to VDD2 via 2 µA current source. |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation architecture | Eliminates optical degradation and startup delays; enables immediate data transmission after power-on. |
| Selectable fail-safe mode | Default-low output state ensures safe shutdown in BMS and traction inverter fault conditions when VDD1 is unpowered. |
| Tri-state outputs with dual enable | EN1 and EN2 allow independent channel grouping control-critical for multiplexed sensor interfaces and clock gating. |
| Ultra-low power at 100 Mbps | 11.7–15.2 mA total supply current at 5 V (VDD1+VDD2) - reduces thermal load in dense PCB layouts. |
| AEC-Q100 Grade 1 qualification | Validated for automotive operation from –40°C to +125°C with zero-defect manufacturing flow and PPAP documentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8652BB-AS1R | Same 3:2 channel count and SOIC-16 NB package, but 2.5 kVRMS isolation rating instead of 3.75 kVRMS. | Suitable for non-reinforced insulation applications such as low-voltage industrial controls where 2.5 kVRMS suffices. | Select SI8652BB-AS1R only if system-level safety certification does not require >2.5 kVRMS working voltage. |
| ADUM141E0BRZ | Four-channel isolator (2:2), 3.75 kVRMS, but no dual-enable architecture and higher 15 ns max propagation delay. | Lacks independent enable control for grouped outputs; less suitable for asymmetric I/O partitioning in BMS. | Choose ADUM141E0BRZ only when channel count matches and dual-enable functionality is unnecessary. |
Compared with SI8652BB-AS1R, SI8652BC-AS1R provides higher isolation margin essential for medical and EV battery systems; compared with ADUM141E0BRZ, it delivers tighter timing control and flexible enable grouping for complex feedback architectures.

What are the enable pin functions on the SI8652BC-AS1R?
The SI8652BC-AS1R features two independent enable inputs: EN1 controls tri-state behavior of outputs A4 and A5 on the input side, while EN2 controls B1–B3 on the output side. Both are internally pulled up to their respective VDD rails with 2 µA current sources and can be left floating, tied high, or driven low for dynamic channel disabling.
