ADUM3402ARWZ Core Benefits Explained

Robust Magnetic Isolation Barrier (iCoupler® Technology)

- Using advanced magnetic inductive coupling technology, completely abandon the traditional optocoupler LED aging problems, longer life, higher stability.

- 2500Vrms high isolation voltage provides strong safety protection and meets stringent electrical safety standards (e.g. UL, CSA, VDE).

- Excellent anti-interference capability: Common-mode transient immunity (CMTI) of 25kV/µs minimum ensures accurate signal transmission in strong noise environments (e.g., motor drive, power conversion) and avoids false triggering.

Enhanced system-level ESD reliability

- Designed to withstand real-world electrostatic shock, it significantly improves the robustness and long-term reliability of the entire system and reduces the field failure rate.

Flexible and efficient four-channel configuration

- 2/2 channel directional assignment (side 1:2 inputs, side 2:2 inputs) Provides design flexibility for bi-directional communications or centralised isolation requirements.

- Unidirectional channel design simplifies interface logic and ensures clear signal flow.

- 1Mbps data rate Meets most medium-speed transmission requirements for control signals, sensor data, status feedback, etc.

Accurate and Fast Signal Transmission

- Maximum propagation delay of 100ns (tpLH/tpHL) and maximum pulse width distortion of 40ns ensure signal timing accuracy.

- Typical rise/fall time of 2.5ns ensures steep and clear signal edges for improved signal quality.

Wide Adaptability and Ease of Integration

- Wide 3V to 5.5V supply voltage range for easy compatibility with 3.3V and 5V systems, simplifying power supply design.

- Industrial-grade temperature range (-40°C ~ +105°C) for extreme operating environments.

- Standard 16-SOIC package for easy automated placement, saving PCB space and speeding up mass production.

ADUM3402ARWZ Typical Application Scenarios

Industrial communication interface isolation: isolation protection for RS-485/422, CAN, SPI, I²C and other buses.

Programmable Logic Controller (PLC) I/O modules: Isolation of digital input/output channels.

Motor drive control: Isolation of PWM signals, fault feedback signals.

Switch-mode power supplies (SMPS): isolate feedback signals and drive signals.

Medical equipment: Signal transmission to meet safety isolation requirements.

Level conversion and isolation between general-purpose systems.
