Product details
Overview
SI8652ED-B-ISR from Skyworks is a five-channel digital isolator with 3 input channels on VDD1 side and 2 output channels on VDD2 side, rated for 5 kVRMS reinforced insulation in wide-body SOIC-16 package. It supports DC–150 Mbps data rates, achieves ≤8 ns typical propagation delay, and operates across –40 to +125 °C with 2.5–5.5 V dual supply rails. It is used in high-reliability isolated power control and motor drive feedback loops.
For engineers reviewing the SI8652ED-B-ISR datasheet, SI8652ED-B-ISR pinout, SI8652ED-B-ISR application, or SI8652ED-B-ISR equivalent, key selection criteria include fail-safe high-default output state, 5 kVRMS isolation rating, tri-state enable control per side, ultra-low power at 100 Mbps (11.7–15.2 mA per side), and AEC-Q100 qualification for automotive BMS and traction inverters.
Technical Context
The SI8652ED-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 architecture delivers precise timing with ≤0.5 ns channel-channel skew and ≤2 ns propagation delay skew between isolated sides.
It features two independent enable inputs (EN1 on Side A, EN2 on Side B) supporting side-specific tri-state control, Schmitt-trigger inputs for >0.44 V hysteresis, and selectable fail-safe mode where outputs default to logic high during VDD1 loss while VDD2 remains powered - confirmed by ordering code "ED".
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels / Direction | 5-channel: 3 inputs on VDD1 side, 2 outputs on VDD2 side |
| Max Data Rate | 150 Mbps - supports high-speed serial interfaces like isolated SPI and RS-485 transceiver control |
| Propagation Delay | 5–13 ns - enables tight-timing feedback in motor gate drivers and ADC sampling clocks |
| Isolation Rating | 5 kVRMS reinforced - certified to UL, VDE, CSA, CQC; suitable for 1000 VAC working voltage systems |
| Supply Voltage Range | 2.5–5.5 V per side - allows interoperability with 3.3 V microcontrollers and 5 V analog front-ends |
| Fail-Safe Default | High - outputs remain logic high during VDD1 undervoltage or loss, critical for safe shutdown in inverters |
| Operating Temperature | –40 to +125 °C - qualified for under-hood automotive and industrial ambient environments |
Pinout & Package
SI8652ED-B-ISR is housed in a RoHS-compliant 16-pin wide-body SOIC package (WB SOIC-16) with 7.5 mm creepage/clearance, supporting reinforced insulation up to 5 kVRMS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Input-side power supply | Supplies 2.5–5.5 V to input-side logic and channel transmitter; bypass requires 0.1 µF capacitor |
| GND1 | Input-side ground reference | Return path for VDD1; must be separated from GND2 by isolation barrier |
| INA1–INA3 | Input signals (Side A) | Three digital inputs accepting 2.0–5.5 V logic; Schmitt-triggered for >0.44 V noise margin |
| EN1 | Input-side enable control | Active-low enable for INA1–INA3 outputs; drives outputs to high-impedance when low |
| VDD2 | Output-side power supply | Supplies 2.5–5.5 V to output-side receiver and driver; independent of VDD1 |
| GND2 | Output-side ground reference | Return path for VDD2; galvanically isolated from GND1 |
| OUTB1–OUTB2 | Isolated output signals (Side B) | Two CMOS outputs with 50 Ω nominal impedance; support 4 mA sink/source |
| EN2 | Output-side enable control | Active-low enable for OUTB1–OUTB2; places outputs in high-Z when low |
| NC | No-connect terminal | Not internally bonded; may be left floating, tied to VDD2, or grounded |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation barrier | Eliminates LED aging and temperature drift; enables 60-year life at rated working voltage |
| Tri-state enable per side | EN1 and EN2 allow independent output disable for power sequencing and bus arbitration |
| Fail-safe high default | Guarantees logic-high outputs during VDD1 failure - prevents unintended gate turn-on in IGBT/MOSFET drivers |
| Ultra-low power at 100 Mbps | 11.7–15.2 mA total supply current (VDD1+VDD2) - reduces thermal load in dense PCB layouts |
| High CMTI immunity | 50 kV/µs common-mode transient immunity - maintains signal integrity in noisy motor drive and inverter environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8652BD-B-IS | Same 3:2 channel count and WB SOIC-16 package, but rated for 5 kVRMS with low-default (BD) fail-safe mode | Outputs default to logic low during VDD1 loss - suitable for active-low enable or reset paths | Select SI8652BD-B-IS when system safety logic requires asserted-low fault signaling during power interruption |
| ADUM141DARZ | 4-channel, 2.5 kVRMS, SOIC-16 narrow body; no selectable fail-safe mode; 100 Mbps max data rate | Lacks reinforced insulation and automotive qualification; not rated for >400 VAC working voltage | Choose ADUM141DARZ only for cost-sensitive industrial designs below 250 VAC isolation requirements |
Compared with SI8652BD-B-IS, SI8652ED-B-ISR provides fail-safe high output behavior essential for preventing false turn-on in power stages; versus ADUM141DARZ, it delivers higher isolation rating, faster data rate, and AEC-Q100 compliance required for automotive traction systems.
