Product details
Overview
MAX22163FAEE+ from Analog Devices is a six-channel reinforced digital isolator with 3kVRMS isolation, 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 from 1.71V–5.5V supplies on both sides, and is qualified for automotive AEC-Q100 Grade 0 (−40°C to +125°C). It enables isolated microcontroller interfaces in battery management systems.
For engineers reviewing the MAX22163FAEE+ datasheet, MAX22163FAEE+ pinout, MAX22163FAEE+ application, or MAX22163FAEE+ equivalent, this device supports high-speed bidirectional isolation in space-constrained automotive and industrial designs requiring reinforced insulation, low power at 1.8V, and robust surge immunity (±10kV).
Technical Context
The MAX22163FAEE+ implements capacitive galvanic isolation using Analog Devices' proprietary process, delivering reinforced insulation per VDE 0884-11 (pending) and UL1577. Its architecture supports independent 1.71V–5.5V supplies on each side, enabling level translation between disparate logic domains without external components.
It integrates undervoltage lockout (1.5V–1.66V threshold) on both VDDA and VDDB, forcing outputs to default-low state during supply faults. The refresh circuit maintains output accuracy during indefinite DC input conditions, ensuring reliable operation in static control signals.

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; 2.5kVRMS isolation; 3.75kV surge rating | Limited to lower-speed industrial I/O; not AEC-Q100 qualified | Select when cost sensitivity outweighs speed/safety requirements and automotive use is excluded |
| ISO6763RWER | 500Mbps max data rate; 5kVRMS isolation; 10kV surge; 3.3V-only supply | Higher performance but lacks 1.8V operation and AEC-Q100 Grade 0 temperature range | Select for high-speed test equipment where extended temperature range is not required |

FAQ
What is the isolation voltage rating of the MAX22163FAEE+?
The MAX22163FAEE+ 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 (1.2/50μs waveform). These ratings are validated per IEC 60747-5-5 and supported by UL1577 and cUL certifications. The MAX22163FAEE+ also meets VDE 0884-11 reinforced insulation requirements (pending final certification).
Does the MAX22163FAEE+ support bidirectional signal flow?
Yes, the MAX22163FAEE+ provides true bidirectional isolation through its channel configuration: three unidirectional channels (IN1–IN3 → OUT1–OUT3) operate from Side A to Side B, and three additional channels (IN4–IN6 → OUT4–OUT6) operate from Side B to Side A. This architecture enables full-duplex isolated communication such as SPI with separate command and response paths, without requiring external direction-control logic.
What is the default output state of the MAX22163FAEE+ during power-up?
The MAX22163FAEE+ features default-low outputs, meaning all six outputs (OUT1–OUT6) assert logic low when either VDDA or VDDB is below the undervoltage lockout threshold (1.5V–1.66V) or when inputs are unpowered/open-circuit. This behavior is guaranteed by internal circuitry and ensures fail-safe operation in safety-critical applications like BMS and inverter control, preventing unintended activation of downstream drivers or actuators.
Can the MAX22163FAEE+ be used for level translation between different logic voltages?
Yes, the MAX22163FAEE+ supports independent 1.71V–5.5V supplies on Side A (VDDA) and Side B (VDDB), allowing seamless level translation between 1.8V, 2.5V, 3.3V, and 5V logic domains. For example, it can interface a 1.8V microcontroller (VDDA = 1.8V) with a 5V CAN transceiver (VDDB = 5V) while maintaining galvanic isolation - eliminating the need for discrete level shifters and reducing BOM count.
Is the MAX22163FAEE+ qualified for automotive applications?
Yes, the MAX22163FAEE+ carries the /V suffix and is fully AEC-Q100 qualified for Grade 0 (−40°C to +125°C ambient), including 100% production testing at both +25°C and +125°C. It is designed for automotive subsystems including battery management, on-board chargers, and traction inverters, and complies with reinforced insulation requirements for functional safety per ISO 26262.
