Skyworks Solutions Inc. SI86S630EE-AS2R

Overview

SI86S630EE-AS2R from Skyworks Solutions is a 3-channel, reinforced-isolation digital isolator with bidirectional signal capability across an integrated semiconductor barrier. It delivers DC–150 Mbps data rate, 10 ns typical propagation delay, and 6000 VRMS isolation rating in a WB SOIC-16 package. Designed for isolated ADC/DAC interfaces and motor control gate drivers in industrial inverters.

For engineers reviewing the SI86S630EE-AS2R datasheet, SI86S630EE-AS2R pinout, SI86S630EE-AS2R application, or SI86S630EE-AS2R equivalent, key selection criteria include fail-safe output configuration (default low), AEC-Q100 qualification, IEC 60747-17 reinforced insulation compliance, and tri-state enable support for bus arbitration.

Technical Context

The SI86S630EE-AS2R implements RF-based on/off keying modulation across a monolithic semiconductor isolation barrier-eliminating startup initialization and enabling robust noise immunity. Its architecture supports independent undervoltage lockout (UVLO) and reset monitoring on both sides (VDD1/VDD2), with RSTB thresholds at ~1.7 V and UVLO hysteresis of 105–160 mV.

All three channels feature Schmitt-trigger + CMOS threshold inputs, 50 Ω nominal output impedance, and selectable fail-safe mode (low-output default per -EE suffix). The device operates across –40 to 125 °C with supply voltage range 2.25–5.5 V and transient immunity ≥100 kV/µs.

FAQ

What is the isolation voltage rating of SI86S630EE-AS2R and which safety standards does it meet?

SI86S630EE-AS2R is rated for 6000 VRMS isolation for 1 minute per UL 1577 and carries reinforced insulation certification per IEC 60747-17, CSA 62368-1, and CQC GB4943.1. This enables use in 1000 VAC systems and meets stringent requirements for medical and EV applications where double insulation is mandated.

Does SI86S630EE-AS2R require external startup initialization or configuration?

No-SI86S630EE-AS2R uses RF on/off keying modulation and requires no firmware, register writes, or power-on calibration. Outputs become active within 0.3 ms after VDD exceeds UVLO+, and default low state is asserted automatically during brownout conditions per its -EE ordering option.

How does the fail-safe mode function in SI86S630EE-AS2R during power loss?

The -EE suffix indicates default-low fail-safe behavior: when either VDD1 or VDD2 drops below UVLO– (1.98–2.12 V), all outputs transition to logic low within 1 µs if VDD remains above RSTB– (~1.7 V), or within 0.3 ms if VDD falls fully below RSTB–. This ensures safe disable of downstream gate drivers or ADC clocks.

What are the supply bypass requirements for SI86S630EE-AS2R?

SI86S630EE-AS2R requires two bypass capacitors per side: 0.1 µF ceramic + 10 µF bulk capacitor placed adjacent to VDD1/GND1 and VDD2/GND2 pins. These suppress high-frequency switching noise and prevent UVLO glitches during transient load events in motor drive or SMPS applications.

Is SI86S630EE-AS2R compatible with 3.3 V and 5 V logic families simultaneously?

Yes-SI86S630EE-AS2R supports 2.25–5.5 V on both VDD1 and VDD2 independently. This allows interfacing a 3.3 V MCU (Side A) with a 5 V isolated gate driver (Side B), or vice versa, without external level shifters-leveraging its CMOS/Schmitt input thresholds and rail-to-rail output swing.
