Product details
Overview
MAX22163FAEE/V+ from Analog Devices is a six-channel reinforced digital isolator with 3kVRMS withstand voltage, 200Mbps maximum data rate, and AEC-Q100 qualification for automotive use. It features three unidirectional channels from Side A to B and three from B to A, operates across 1.71V–5.5V dual supplies, and delivers 7ns typical propagation delay at 3.3V for isolated microcontroller interfaces in battery management systems.
For engineers reviewing the MAX22163FAEE/V+ datasheet, MAX22163FAEE/V+ pinout, MAX22163FAEE/V+ application, or MAX22163FAEE/V+ equivalent, this page provides verified isolation ratings, channel direction mapping, CMTI (50kV/μs), power consumption per channel (0.71mW @1Mbps/1.8V), and AEC-Q100 compliance details critical for automotive BMS and inverter design.
Technical Context
The MAX22163FAEE/V+ implements reinforced galvanic isolation using Analog Devices' proprietary silicon process, supporting independent 1.71V–5.5V supplies on both sides for level translation. Its six unidirectional channels are split 3A→B / 3B→A, enabling bidirectional communication between isolated domains without external logic.
It features undervoltage lockout (1.5V–1.66V threshold) on both VDDA and VDDB, default-low outputs ('F' suffix), and a refresh circuit ensuring output stability during indefinite DC input states-critical for safety-critical automotive applications operating from −40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 3kVRMS for 60s (UL1577, VDE 0884-11 pending); enables safe separation of high-voltage battery domains from low-voltage MCU control circuits |
| Max Data Rate | 200Mbps (C/F variant); supports high-speed isolated SPI or CAN FD signaling in EV inverters |
| Propagation Delay | 7ns typical at VDD = 3.3V; reduces system latency in real-time BMS cell monitoring loops |
| CMTI | 50kV/μs typical; maintains signal integrity during fast-switching transients in motor drives |
| Supply Range | 1.71V–5.5V per side; allows direct interfacing with 1.8V MCUs and 3.3V/5V peripherals without level shifters |
| Power @1Mbps | 0.71mW/channel @1.8V; cuts total isolation power by >40% vs. legacy isolators in always-on BMS monitoring |
| Output Default | Default-low ('F' suffix); ensures safe low-state output during power-up, brownout, or open-input conditions |
Pinout & Package
Package: 16-pin QSOP with 4mm creepage and clearance, RoHS-compliant (E16MS+2 outline), rated for −40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDA (Pin 1) | Side A power supply input | Bypass with 0.1µF capacitor to GNDA; sets logic-high level for IN1–IN3 and OUT1–OUT3 |
| IN1–IN3 (Pins 2–4) | Unidirectional inputs (A→B) | Drive corresponding OUT1–OUT3 on Side B; support 1.71V–5.5V logic thresholds |
| IN4–IN6 (Pins 5–7) | Unidirectional inputs (B→A) | Receive signals from Side B; drive OUT4–OUT6 on Side A (reverse-direction channels) |
| GNDA (Pin 8) | Side A ground reference | Return path for VDDA and A-side I/O; must be isolated from GNDB by PCB layout |
| GNDB (Pin 9) | Side B ground reference | Return path for VDDB and B-side I/O; forms reinforced isolation barrier with GNDA |
| OUT4–OUT6 (Pins 10–12) | Unidirectional outputs (A←B) | Driven by IN4–IN6; deliver logic levels referenced to VDDA, enabling A-side readback of B-side signals |
| OUT1–OUT3 (Pins 13–15) | Unidirectional outputs (A→B) | Driven by IN1–IN3; push-pull outputs eliminate need for external pull-ups in SPI/MCU interfaces |
| VDDB (Pin 16) | Side B power supply input | Bypass with 0.1µF capacitor to GNDB; sets logic-high level for IN4–IN6 and OUT4–OUT6 |
Key Features

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 |
|---|---|---|---|
| SI8661ED-B-IS | 25Mbps max data rate (vs. 200Mbps); 2.5kVRMS isolation; no AEC-Q100 qualification | Suitable for non-automotive industrial SPI where speed <50Mbps suffices | Select when cost sensitivity outweighs speed/safety requirements and automotive qualification is unnecessary |
| ISO6760FDWER | 6-channel, 50Mbps, 5kVRMS; AEC-Q100 Grade 1; default-high outputs | Requires external pull-downs for default-low behavior; higher isolation but lower speed than MAX22163FAEE/V+ | Choose for applications needing >4.5kVRMS rating and Grade 1 temperature range, accepting 50Mbps limit and output polarity mismatch |
Compared with SI8661ED-B-IS and ISO6760FDWER, the MAX22163FAEE/V+ uniquely combines AEC-Q100 Grade 0 qualification, 200Mbps speed, default-low safety state, and 3kVRMS reinforced isolation in a single 16-QSOP package-making it optimal for next-generation EV battery and inverter control.

FAQ
What is the isolation voltage rating of the MAX22163FAEE/V+?
The MAX22163FAEE/V+ has a reinforced isolation rating of 3000VRMS for 60 seconds (VISO), continuously withstands 445VRMS (VIOWM), and survives ±10kV surge (1.2/50μs) between GNDA and GNDB. These values are certified per UL1577 and pending VDE 0884-11, making it suitable for automotive high-voltage domain separation.
Does the MAX22163FAEE/V+ support level shifting between different logic voltages?
Yes, the MAX22163FAEE/V+ supports true level shifting: VDDA (1.71V–5.5V) and VDDB (1.71V–5.5V) operate independently, allowing 1.8V MCU signals on Side A to interface with 3.3V or 5V peripherals on Side B without external translators-enabling flexible mixed-voltage system design.
What does the 'F' in MAX22163FAEE/V+ indicate?
The 'F' suffix denotes default-low output behavior: when either VDDA or VDDB is below UVLO threshold (1.5V–1.66V) or inputs are unpowered/open, all outputs assert low. This fail-safe state is critical for automotive ASIL-B/C systems where unintended high signals could trigger hazardous actuation.
Is the MAX22163FAEE/V+ pin-compatible with other devices in the MAX22163–MAX22166 family?
Yes, all MAX22163–MAX22166 variants-including MAX22163FAEE/V+, MAX22164FAEE/V+, and MAX22166FAEE/V+-share identical 16-QSOP pinout and package (E16MS+2). Channel direction (A→B vs. B→A) differs per part number, but PCB layout and footprint remain interchangeable across the family.
What safety certifications does the MAX22163FAEE/V+ hold?
The MAX22163FAEE/V+ is certified to UL1577 (3000VRMS) and CSA Bulletin 5A (cUL), with VDE 0884-11 reinforced insulation certification pending. It meets AEC-Q100 Grade 0 (−40°C to +125°C) and supports functional safety development per ISO 26262 when used per manufacturer guidelines.
