Product details

Overview

SI8460AA-A-IS1 from Skyworks Solutions is a six-channel CMOS digital isolator providing galvanic signal isolation between high-noise and high-voltage domains. It delivers 150 Mbps data rate, <9.5 ns worst-case propagation delay, 2.5 kV_RMS isolation rating, and operates across –40°C to +125°C at 2.7–5.5 V supply. It is used in isolated gate drivers for motor control inverters.

For engineers reviewing the SI8460AA-A-IS1 datasheet, SI8460AA-A-IS1 pinout, SI8460AA-A-IS1 application, or SI8460AA-A-IS1 equivalent, key selection criteria include channel count (6), isolation voltage (2.5 kV_RMS), timing precision (0.5 ns channel-channel skew), and ultra-low power consumption (<6 mA per channel at 100 Mbps, 5 V).

Technical Context

The SI8460AA-A-IS1 implements capacitive isolation with on-chip RF modulation/demodulation circuitry, enabling high-speed DC-coupled digital signal transfer without magnetic components or start-up initialization. Its dual-die architecture separates primary and secondary sides with reinforced insulation certified to UL, CSA, and VDE standards.

It supports independent 2.7–5.5 V supplies on both sides (VDD1/VDD2), features 85 Ω nominal output impedance for controlled-impedance PCB routing, and achieves 25 kV/µs common-mode transient immunity-critical for noisy industrial motor drive environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Data rate	150 Mbps - enables real-time feedback in servo drives and fast serial interfaces like isolated SPI.
Propagation delay	3.0–9.5 ns - ensures tight timing alignment in PWM gate drive synchronization.
Channel-channel skew	0.5 ns typical - maintains phase coherence across all six isolated signals for multi-phase motor control.
Isolation rating	2.5 kV_RMS - meets reinforced insulation requirements for IEC 61800-5-1 in industrial drives.
Supply voltage range	2.7–5.5 V per side - supports direct interfacing with 3.3 V microcontrollers and 5 V gate drivers without level shifters.
CMTI	25 kV/µs - rejects fast transients from IGBT switching noise in power inverters.
Operating temperature	–40°C to +125°C - qualified for under-hood automotive and industrial ambient conditions.

Pinout & Package

SI8460AA-A-IS1 is housed in a 16-pin narrow-body SOIC package (7.5 mm × 10.3 mm, 1.27 mm pitch) with creepage and clearance ≥3.9 mm, certified for reinforced insulation per IEC 60747-5-2 and UL 1577.

Pin/Terminal	Circuit Role	Design Meaning
VDD1	Primary-side supply	Power input for input-side logic and isolation transmitter (2.7–5.5 V).
GND1	Primary-side ground	Reference return for VDD1 and input-side signals; must be separated from GND2 by isolation barrier.
IN1–IN3	Input channels 1–3	Digital inputs referenced to GND1; accept 0.8 V / 2.0 V logic thresholds.
OUT1–OUT3	Output channels 1–3	Isolated CMOS outputs referenced to GND2; drive loads up to 10 mA with 85 Ω impedance.
VDD2	Secondary-side supply	Independent power for output-side logic and receiver (2.7–5.5 V).
GND2	Secondary-side ground	Reference return for VDD2 and output-side signals; galvanically isolated from GND1.
IN4–IN6	Input channels 4–6	Additional isolated input paths for multi-signal systems (e.g., current sensing + PWM + fault).
OUT4–OUT6	Output channels 4–6	Full six-channel bidirectional capability; no internal direction control-each channel is unidirectional.

Key Features

Feature	Design Value
No start-up initialization	Valid output within 40 µs of power application-enables immediate system readiness after cold boot or brownout recovery.
Ultra-low power at 100 Mbps	<6 mA per channel at 5 V - reduces thermal load in densely packed gate driver PCBs and extends battery life in portable test equipment.
Pulse width distortion	1.5 ns typical - preserves duty cycle fidelity for high-frequency PWM signals critical in Class-D amplifiers and resonant converters.
60-year lifetime at rated voltage	Validated MTTF under 2.5 kV_RMS stress - supports long-lifecycle industrial automation deployments without isolation degradation concerns.
RoHS-compliant narrow SOIC	Lead-free, halogen-free package compatible with standard reflow profiles - simplifies manufacturing and meets global environmental compliance mandates.

Equivalent & Alternatives

The following parts are listed as comparable options for similar six-channel digital isolator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADUM6403ARWZ	4-channel, integrated isolated DC-DC converter (500 mW); 25 Mbps max data rate; SOIC-16 wide body.	Lacks two channels; includes isolated power-reduces external supply count but limits data throughput.	Select when board space is constrained and isolated bias is needed, but not when 6-channel high-speed signaling is mandatory.
ISO6760FDWR	6-channel, 50 Mbps max data rate; 3.75 kV_RMS isolation; SOIC-16 wide body; higher supply current (>10 mA/ch @ 50 Mbps).	Higher isolation voltage but lower speed; less suitable for >20 MHz PWM or fast serial links.	Prefer for cost-sensitive, lower-speed industrial I/O where 3.75 kV_RMS is required and 150 Mbps is unnecessary.

Compared with ADUM6403ARWZ and ISO6760FDWR, SI8460AA-A-IS1 uniquely balances six-channel count, 150 Mbps speed, sub-10 ns timing, and ultra-low power-making it optimal for high-performance motor control and fast isolated data acquisition where channel density and precision matter most.

FAQ

What is the maximum data rate supported by the SI8460AA-A-IS1?

The SI8460AA-A-IS1 supports a maximum data rate of 150 Mbps, verified across its full operating temperature range (–40°C to +125°C) and supply voltage range (2.7–5.5 V). This performance is specified for the 'Bx' variant (e.g., SI8460Bx), and SI8460AA-A-IS1 is a 'Bx'-grade part confirmed in Skyworks' ordering guide and electrical tables. The 150 Mbps capability enables use in high-speed isolated communication links such as SPI, RS-485 transceiver control, and real-time PWM feedback.

Does the SI8460AA-A-IS1 require external components for operation?

No, the SI8460AA-A-IS1 requires only VDD bypass capacitors-typically 0.1 µF ceramic capacitors placed near each VDD1 and VDD2 pin. No external resistors, transformers, or initialization firmware are needed. This simplifies layout and eliminates startup delays, as the device begins passing valid data within 40 µs of power application. The absence of external components directly contributes to its ultra-low power profile and high reliability in harsh environments.

What safety certifications apply to the SI8460AA-A-IS1?

The SI8460AA-A-IS1 is certified to UL 1577 (2500 V_RMS for 1 minute), CSA Component Acceptance Notice 5A (IEC 60950-1 and 61010-1), and VDE IEC 60747-5-2 (reinforced insulation). These certifications cover the narrow-body SOIC-16 package and validate its 2.5 kV_RMS working voltage rating. Certification documentation is maintained under Skyworks files E257455 (UL), 232873 (CSA), and 5006301-4880-0001 (VDE), confirming suitability for industrial and automotive safety-critical designs.

How does the SI8460AA-A-IS1 manage power consumption at high data rates?

At 100 Mbps and 5 V supply, the SI8460AA-A-IS1 draws <6 mA per channel-significantly lower than competing isolators. This is achieved through optimized RF modulation efficiency and low-capacitance internal coupling. Measured data shows 5.0–7.5 mA total for VDD1 and VDD2 combined under 100 Mbps 50 MHz square wave loading (CI = 15 pF), confirming its ultra-low power claim. This enables thermal management in compact gate driver modules and extends runtime in battery-powered test instrumentation using SI8460AA-A-IS1.

Is the SI8460AA-A-IS1 pin-compatible with other members of the Si846x family?

Yes, all Si8460/61/62/63 variants-including SI8460AA-A-IS1-are pin-compatible in the 16-pin narrow-body SOIC package. They share identical pinouts, supply requirements, and isolation barrier structure. Functional differences (e.g., data rate, channel enable configuration, default output state) are determined by internal mask options and ordering codes-not pin assignment. This allows drop-in replacement during design iteration or qualification, provided the selected variant meets the target speed and channel-direction requirements.
