Product details
Overview
MAX22163CAEE+ from Analog Devices is a six-channel reinforced digital isolator with 3kVRMS withstand voltage, 200Mbps maximum data rate, and 50kV/μs CMTI. 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 is qualified for automotive (-40°C to +125°C) use in isolated microcontroller interfaces.
For engineers reviewing the MAX22163CAEE+ datasheet, MAX22163CAEE+ pinout, MAX22163CAEE+ application, or MAX22163CAEE+ equivalent, this device delivers high-speed bidirectional isolation with low power (0.71mW/channel @1Mbps, 1.8V), precise timing (7ns typ propagation delay), and safety-certified reinforced insulation for BMS, inverters, and industrial fieldbus systems.
Technical Context
The MAX22163CAEE+ implements capacitive galvanic isolation using Analog Devices' proprietary process, supporting independent 1.71V–5.5V supplies on both sides for level-shifting functionality. Its architecture includes six unidirectional channels-three A→B and three B→A-with push-pull outputs eliminating external pull-ups.
It features undervoltage lockout (1.5V–1.66V threshold) on both VDDA and VDDB, default-high output behavior (C/F variant), and a refresh circuit ensuring output stability during indefinite DC input states. Safety compliance includes UL1577 (3kVRMS), cUL, and pending VDE 0884-11 reinforced insulation certification.

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 | 250Mbps max rate; 5kVRMS isolation; 2.5V–5.5V supply only; no 1.8V support | Higher speed but lacks 1.8V compatibility and automotive temperature range (–40°C to +105°C only) | Select when 250Mbps and 5kVRMS are mandatory, and 1.8V logic is not used. |
| ISO6763RQWR | 50Mbps max rate; 5000VRMS; 1.71V–5.5V; default-low outputs; no AEC-Q100 qualification | Lower speed, no automotive qualification, and incompatible default state for fail-safe MCU interfaces | Select for cost-sensitive industrial applications where 200Mbps and AEC-Q100 are unnecessary. |

FAQ
What is the isolation voltage rating of the MAX22163CAEE+?
The MAX22163CAEE+ has a reinforced isolation rating of 3kVRMS for 60 seconds (VISO), a maximum working voltage of 445VRMS (VIOWM), and withstands ±10kV surge per IEC 61000-4-5. These ratings are certified under UL1577 and pending VDE 0884-11, making MAX22163CAEE+ suitable for high-voltage automotive and industrial barrier applications.
Does the MAX22163CAEE+ support 1.8V logic on both sides?
Yes, the MAX22163CAEE+ supports independent 1.71V–5.5V supplies on both VDDA and VDDB, enabling true 1.8V operation on either side. This allows direct interfacing with low-voltage microcontrollers and sensors without level-shifting components - a key capability confirmed in the DC Electrical Characteristics table for MAX22163CAEE+.
What is the channel configuration of the MAX22163CAEE+?
The MAX22163CAEE+ provides three unidirectional channels from Side A to Side B (IN1→OUT1, IN2→OUT2, IN3→OUT3) and three from Side B to Side A (IN4→OUT4, IN5→OUT5, IN6→OUT6). This bidirectional 3+3 configuration is optimized for isolated microcontroller interfaces requiring command and feedback paths across the isolation barrier.
Is the MAX22163CAEE+ AEC-Q100 qualified?
Yes, the MAX22163CAEE+ carries the /V suffix indicating AEC-Q100 qualification for automotive applications. It is rated for operation from –40°C to +125°C ambient temperature and undergoes 100% production testing at both +25°C and +125°C, fulfilling reliability requirements for EV battery and powertrain systems.
What is the default output state of the MAX22163CAEE+?
The MAX22163CAEE+ is a C/F variant and features default-high outputs. When either VDDA or VDDB is below undervoltage lockout threshold (1.5V–1.66V), all outputs transition to high - a fail-safe behavior critical for enabling controlled shutdown in automotive and industrial control systems using MAX22163CAEE+.
