Product details
Overview
SI86S662BB-AUR from Skyworks Solutions is a 6-channel reinforced digital isolator with bidirectional signal isolation across an integrated semiconductor barrier. It supports DC to 150 Mbps data rates, delivers 10 ns typical propagation delay, and provides 6000 VRMS isolation rating in a WB SOIC-16 package. It is used in battery management systems and traction inverters where high-speed, fail-safe isolated communication between MCU and power stage is required.
For engineers reviewing the SI86S662BB-AUR datasheet, SI86S662BB-AUR pinout, SI86S662BB-AUR application, or SI86S662BB-AUR equivalent, key selection criteria include reinforced IEC 60747-17 certification, AEC-Q100 qualification, selectable fail-safe output mode (default high/low), tri-state outputs with enable, and compatibility with industrial and automotive isolated ADC/DAC interfaces.
Technical Context
The SI86S662BB-AUR implements RF-based on/off keying modulation across a monolithic semiconductor isolation barrier, eliminating startup initialization and enabling robust noise immunity. It features independent undervoltage lockout (UVLO) and reset circuitry on both sides (VDD1/VDD2), with UVLO+ = 2.18 V and RSTB– ≈ 1.7 V.
It supports dual-supply operation from 2.25 V to 5.5 V per side, includes Schmitt-trigger + CMOS threshold inputs for enhanced noise rejection, and offers tri-state output control via EN1/EN2 pins. Fail-safe default output state (high or low) is determined by ordering option and latched during unpowered conditions on the input side.

FAQ
What is the isolation voltage rating of SI86S662BB-AUR and which safety standards does it meet?
SI86S662BB-AUR provides 6000 VRMS isolation for 1 minute per UL 1577 and is certified to IEC 60747-17 for reinforced insulation. It also complies with CSA 62368-1 and 60601-1, and CQC GB4943.1. These approvals validate its use in safety-critical automotive and medical applications where reinforced barrier integrity is mandated.
Does SI86S662BB-AUR support fail-safe output behavior during power loss?
Yes, SI86S662BB-AUR offers a selectable fail-safe mode defined at order time: default high or default low output state when VDD1 is unpowered but VDD2 remains active. This behavior is implemented via internal latching and ensures predictable system response during MCU brownout or reset sequences in battery management systems.
What are the supply voltage requirements for SI86S662BB-AUR?
SI86S662BB-AUR operates with independent 2.25 V to 5.5 V supplies on both sides (VDD1 and VDD2). Each side requires local 0.1 µF ceramic + 10 µF bulk bypass capacitors. The device maintains full functionality across this range, enabling direct interfacing with 3.3 V microcontrollers and 5 V peripheral logic without external level translation.
How many channels does SI86S662BB-AUR provide and what is their directionality?
SI86S662BB-AUR provides six unidirectional channels: A1–A6 on the input (Side A) side and B1–B6 on the output (Side B) side. All channels transmit from Side A to Side B only. Directionality is fixed and cannot be reversed; for bidirectional isolation, consider Si86SQ44 or Si86SS51 variants.
Is SI86S662BB-AUR qualified for automotive applications?
Yes, SI86S662BB-AUR is AEC-Q100 qualified (Grade 1, –40 °C to +125 °C) and manufactured using automotive-specific process flows. It supports AIAG-compliant PPAP documentation and IMDS/CAMDS reporting-making it suitable for onboard chargers, battery management systems, and traction inverters in BEV/HEV platforms.
