Product details
Overview
MAX22166FAEE+ from Analog Devices is a six-channel, unidirectional, reinforced digital isolator in 16-QSOP package with 3kVRMS withstand voltage, 200Mbps maximum data rate, and 50kV/μs CMTI. It isolates digital signals between separate power domains in high-noise automotive BMS and industrial motor control systems.
For engineers reviewing the MAX22166FAEE+ datasheet, MAX22166FAEE+ pinout, MAX22166FAEE+ application, or MAX22166FAEE+ equivalent, this page delivers verified channel configuration (6× unidirectional A→B), supply flexibility (1.71V–5.5V per side), low-power operation (0.75mW/channel @1.8V/1Mbps), and safety-certified reinforced insulation.
Technical Context
The MAX22166FAEE+ implements proprietary capacitive isolation technology with reinforced barrier rated to 3kVRMS for 60s and 445VRMS continuous working voltage. Its six independent unidirectional channels transmit exclusively from Side A (IN1–IN6) to Side B (OUT1–OUT6), eliminating bidirectional contention and simplifying timing analysis in isolated SPI or digital I/O interfaces.
It features dual independent supplies (VDDA/GNDA and VDDB/GNDB), undervoltage lockout with 1.6V threshold and 45mV hysteresis, and push-pull outputs capable of driving TTL/CMOS loads without external pull-ups. The device maintains 7ns typical propagation delay at 3.3V and 11.1ps RMS clock jitter for low-latency deterministic communication.
Key Specifications

| IN1–IN6 (Pins 2–4, 12–10) | Unidirectional digital inputs (Side A) | Accept CMOS/TTL logic; drive corresponding OUT1–OUT6 on Side B; no internal pull-up/down |
| GNDA (Pin 8) | Side A ground reference | Return path for VDDA and all Side A inputs; must be separated from GNDB by isolation barrier |
| GNDB (Pin 9) | Side B ground reference | Return path for VDDB and all Side B outputs; galvanically isolated from GNDA |
| OUT1–OUT6 (Pins 15–13, 5–7) | Unidirectional digital outputs (Side B) | Push-pull drivers; default-low state when VDDA or VDDB is below UVLO threshold |
| VDDB (Pin 16) | Side B power supply input | Bypass with 0.1µF capacitor to GNDB; sets logic-high level on output side (1.71V–5.5V) |

FAQ
What is the maximum data rate supported by the MAX22166FAEE+?
The MAX22166FAEE+ supports a maximum data rate of 200Mbps under conditions of 2.25V ≤ VDD ≤ 5.5V. This high-speed capability enables its use in demanding applications such as isolated SPI interfaces and real-time digital I/O in automotive and industrial systems. The MAX22166FAEE+ achieves this while maintaining low jitter (11.1ps RMS) and tight propagation delay matching across all six channels.
Does the MAX22166FAEE+ have AEC-Q100 qualification?
Yes, the MAX22166FAEE+ is AEC-Q100 qualified (Grade 1, –40°C to +125°C ambient). The "/V" suffix in the part number indicates automotive qualification, and the device is fully specified and tested across temperature for automotive applications including battery management systems and onboard chargers. This qualification ensures reliability in harsh automotive environments.
What is the default output state of the MAX22166FAEE+ during undervoltage conditions?
The MAX22166FAEE+ features default-low outputs (denoted by the "F" in the part number). During undervoltage lockout on either VDDA or VDDB, all six outputs (OUT1–OUT6) transition to and hold a logic-low state regardless of input conditions. This behavior is defined in Table 2 of the datasheet and ensures fail-safe operation in power-fail scenarios.
Can the MAX22166FAEE+ be used for level translation between different voltage domains?
Yes, the MAX22166FAEE+ supports level translation via independent VDDA (1.71V–5.5V) and VDDB (1.71V–5.5V) supplies. For example, it can translate 1.8V logic from a microcontroller (Side A) to 3.3V or 5V logic on the isolated side (Side B), or vice versa. This eliminates the need for external level shifters in mixed-voltage isolated interfaces.
What safety certifications does the MAX22166FAEE+ hold?
The MAX22166FAEE+ is certified to UL 1577 (3000VRMS), cUL CSA Bulletin 5A, and pending VDE 0884-11 reinforced insulation. It meets IEC 60747-5-5 requirements with VIOWM = 445VRMS, VISO = 3000VRMS, and surge rating of ±10kV (1.2/50μs). These certifications validate its suitability for reinforced isolation in safety-critical automotive and industrial applications.
