Product details
Overview
MAX22164EAEE+ from Analog Devices is a six-channel reinforced digital isolator with 4-channel A→B and 2-channel B→A unidirectional signal transfer, 200Mbps maximum data rate, 7ns typical propagation delay at 3.3V, and 50kV/μs CMTI. It operates across 1.71V–5.5V dual supplies and is used in isolated SPI interfaces for battery management systems.
For engineers reviewing the MAX22164EAEE+ datasheet, MAX22164EAEE+ pinout, MAX22164EAEE+ application, or MAX22164EAEE+ equivalent, this page delivers verified specifications, QSOP-16 pin mapping, automotive-grade isolation performance, and real-world design context for high-reliability BMS and inverter gate drive circuits.
Technical Context
The MAX22164EAEE+ implements capacitive galvanic isolation using Analog Devices' proprietary process, supporting independent 1.71V–5.5V VDDA and VDDB supplies for level translation. Its 4:2 channel directionality enables bidirectional protocol isolation like SPI without external logic.
It features default-low outputs (E/F suffix), undervoltage lockout (1.5V–1.66V threshold), and a refresh circuit ensuring output stability during static input conditions-critical for safety-critical automotive applications operating from −40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 3000VRMS for 60s - meets reinforced insulation requirements per IEC 60747-5-5 and UL1577. |
| Working Voltage | 445VRMS continuous - supports long-term operation in high-noise industrial bus environments. |
| Max Data Rate | 200Mbps - enables high-speed isolated communication for real-time BMS cell monitoring. |
| Propagation Delay | 7ns typ at 3.3V - reduces system latency in fast-switching inverter control loops. |
| CMTI | 50kV/μs typ - rejects common-mode transients from motor drives and DC-DC converters. |
| Supply Range | 1.71V–5.5V per side - allows direct interfacing with 1.8V microcontrollers and 3.3V/5V peripherals. |
| Power @ 1Mbps | 0.71mW/channel at 1.8V - cuts total isolation power by >40% vs. legacy optocouplers in portable BMS. |
Pinout & Package
Package: 16-pin QSOP (E16MS+2), 4mm creepage and clearance, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDA (Pin 1) | Side A power supply | Bypass with 0.1µF capacitor to GNDA; sets logic-high level on input side (IN1–IN6). |
| IN1–IN3 (Pins 2–4) | Unidirectional inputs (A→B) | Drive OUT1–OUT3 on Side B; support 200Mbps data transfer with 7ns delay. |
| IN4–IN6 (Pins 5–7) | Unidirectional inputs (B→A) | Receive signals from Side B; enable full-duplex SPI clock/data isolation. |
| GNDA (Pin 8) | Side A ground reference | Return path for VDDA and IN1–IN6; must be separated from GNDB for isolation integrity. |
| GNDB (Pin 9) | Side B ground reference | Return path for VDDB and OUT1–OUT6; forms galvanic barrier with GNDA. |
| OUT1–OUT3 (Pins 13–15) | Unidirectional outputs (A→B) | Push-pull CMOS/TTL-compatible outputs; no pull-up resistors required. |
| OUT4–OUT6 (Pins 5, 6, 12) | Unidirectional outputs (B→A) | Match IN4–IN6 directionality; support isolated feedback paths in closed-loop systems. |
| VDDB (Pin 16) | Side B power supply | Bypass with 0.1µF capacitor to GNDB; sets logic-high level on output side (OUT1–OUT6). |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced Isolation | 3000VRMS withstand voltage certified to UL1577 and CSA Bulletin 5A - enables single-barrier safety compliance in EV traction inverters. |
| Default-Low Outputs | E/F suffix ensures outputs go low during undervoltage or open-input conditions - prevents unintended gate activation in motor drivers. |
| Low-Power Operation | 0.71mW/channel at 1.8V/1Mbps - extends battery life in wireless BMS sensor nodes and reduces thermal load in dense PCB layouts. |
| High CMTI | 50kV/μs typical - maintains signal integrity in 800V EV architectures with fast-switching SiC MOSFETs generating >50kV/μs dV/dt. |
| Independent Dual Supplies | VDDA and VDDB each 1.71V–5.5V - eliminates level-shifter ICs when interfacing 1.8V MCUs with 5V analog front-ends. |

FAQ
What is the isolation voltage rating of the MAX22164EAEE+?
The MAX22164EAEE+ has a reinforced isolation rating of 3000VRMS for 60 seconds (VISO), a maximum working voltage of 445VRMS (VIOWM), and a surge withstand capability of ±10kV between GNDA and GNDB. These values are certified per UL1577 and CSA Bulletin 5A, with VDE 0884-11 reinforced approval pending.
Does the MAX22164EAEE+ support level shifting between different logic voltages?
Yes, the MAX22164EAEE+ supports true level shifting: VDDA and VDDB operate independently from 1.71V to 5.5V, allowing seamless interface between 1.8V microcontrollers and 3.3V or 5V peripherals without external level translators-enabling mixed-voltage system designs.
What does the "E" and "AEE+" suffix indicate in MAX22164EAEE+?
The "E" denotes default-low output behavior during undervoltage or open-input conditions. "AEE+" specifies the 16-pin QSOP package (E), automotive-grade temperature range (−40°C to +125°C), and RoHS-compliant + suffix. This confirms its suitability for automotive BMS and inverter applications.
How many channels of the MAX22164EAEE+ are directional, and what is their configuration?
The MAX22164EAEE+ has six unidirectional channels: four transmit from Side A to Side B (IN1–IN4 → OUT1–OUT4), and two transmit from Side B to Side A (IN5–IN6 → OUT5–OUT6). This 4:2 configuration is optimized for isolated SPI, where clock, MOSI, and CS flow A→B while MISO and ready signals flow B→A.
Is the MAX22164EAEE+ qualified for automotive applications?
Yes, the MAX22164EAEE+ is AEC-Q100 qualified for automotive use (Grade 0: −40°C to +125°C ambient), with reinforced isolation, 445VRMS working voltage, and 3000VRMS withstand rating-meeting critical safety requirements for hybrid/electric vehicle battery management and traction inverter systems.
