Product details

Overview

SI8462BB-B-IS1R from Skyworks Solutions is a six-channel, ultra-low-power digital isolator in a 16-pin narrow-body SOIC package, supporting up to 150 Mbps data rate with worst-case propagation delay <9.5 ns, 0.5 ns channel-to-channel skew, and 25 kV/µs common-mode transient immunity. It operates across 2.70–5.5 V supply rails and delivers <13.3 mA per side at 100 Mbps (5 V), enabling high-speed isolation in motor control and isolated power supplies.

For engineers reviewing the SI8462BB-B-IS1R datasheet, SI8462BB-B-IS1R pinout, SI8462BB-B-IS1R application, or SI8462BB-B-IS1R equivalent, key selection criteria include its 2500 VRMS reinforced insulation rating (UL/CSA/VDE certified), 6-channel unidirectional configuration (3 channels per side), and operation over –40 to +125 °C at full speed-critical for industrial inverters and isolated ADC interfaces.

Technical Context

The SI8462BB-B-IS1R implements capacitive isolation using RF modulation/demodulation across an on-chip SiO₂ barrier, eliminating magnetic coupling and start-up initialization. Its architecture supports independent primary-side (VDD1) and secondary-side (VDD2) supplies, each configurable from 2.70 V to 5.5 V, with no shared ground requirement.

All six channels are unidirectional and fixed-direction: channels 1–3 (pins 1–3, 16–14) transmit from side 1 to side 2; channels 4–6 (pins 4–6, 13–11) transmit from side 2 to side 1. Timing performance-including 1.5 ns typical pulse width distortion and 6 ns minimum pulse width-is guaranteed across temperature and voltage extremes without derating.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADUM260N0BRIZ-RL	6-channel, 25 Mbps max, 2.5 kVRMS, SOIC-16; higher propagation delay (25 ns typ), lower CMTI (100 kV/µs).	Targeted at cost-sensitive industrial I/O where speed <25 Mbps suffices; lacks 150 Mbps capability for high-fidelity motor control.	Select when budget constraints outweigh need for >100 Mbps throughput and sub-10 ns timing.
ISO6760FDWR	6-channel, 50 Mbps max, 5 kVRMS, SOIC-16; higher isolation rating but slower speed and larger package footprint (7.5 mm width).	Suitable for medical or test equipment requiring >3.75 kVRMS working voltage; incompatible with space-constrained motor control PCBs.	Choose only if regulatory requirements mandate >3.75 kVRMS isolation and 50 Mbps is sufficient for system timing.

Compared with ADUM260N0BRIZ-RL and ISO6760FDWR, SI8462BB-B-IS1R uniquely balances 150 Mbps speed, 2500 VRMS certification, and SOIC-16NB compactness-making it optimal for high-density, high-speed industrial and automotive isolation where timing precision and thermal efficiency are critical.

FAQ

What is the maximum data rate supported by SI8462BB-B-IS1R?

The SI8462BB-B-IS1R supports a maximum data rate of 150 Mbps across all six channels under specified operating conditions (VDD = 5 V, TA = –40 to +125 °C, CL = 15 pF). This is confirmed in Table 3 and Table 4 timing characteristics for Si8462Bx variants, and applies to both side-1-to-side-2 and side-2-to-side-1 channels in the SI8462BB-B-IS1R configuration.

Does SI8462BB-B-IS1R require external components for basic operation?

Yes, SI8462BB-B-IS1R requires external 0.1 µF bypass capacitors on both VDD1 and VDD2 pins, placed as close as possible to the device per Skyworks layout recommendations. No pull-up/down resistors, termination networks, or initialization firmware are needed-the SI8462BB-B-IS1R begins transmitting valid data within 40 µs of power application.

What safety certifications does SI8462BB-B-IS1R hold?

SI8462BB-B-IS1R is certified to UL 1577 (2500 VRMS, File E257455), CSA Component Notice 5A (IEC 60950-1/61010-1), and VDE IEC 60747-5-2 (File 5006301-4880-0001). These apply to the 2.5 kVRMS-rated narrow-body SOIC-16 package and are verified through production testing at 3.0 kVRMS for 1 second.

How many channels does SI8462BB-B-IS1R have, and what is their directionality?

SI8462BB-B-IS1R has six unidirectional channels: CH1–CH3 transmit from side 1 (VDD1) to side 2 (VDD2); CH4–CH6 transmit from side 2 (VDD2) to side 1 (VDD1). This fixed 3+3 configuration is defined in the Si8462Bx variant specification and confirmed in pin descriptions on page 27 of the datasheet.

Is SI8462BB-B-IS1R suitable for automotive applications?

SI8462BB-B-IS1R operates over –40 to +125 °C at full 150 Mbps data rate and meets reinforced insulation requirements for functional safety systems. While not AEC-Q100 qualified itself, it is used in hybrid electric vehicle traction inverters per Skyworks' application guidance; design-in requires system-level qualification per ASIL-B/C requirements.
