[In Stock] Mingjiada Supply ADUM2250ARWZ (ADI) Hot Swappable Digital Isolators

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of ADI (ADUM2250ARWZ) hot-swappable, dual-channel I²C digital isolators.

Product Details:

The ADUM2250ARWZ is a hot-swappable digital isolator featuring built-in non-latching bidirectional communication channels. It integrates two bidirectional communication channels utilising ADI's proprietary iCoupler® magnetic isolation technology. The ADUM2250ARWZ achieves signal and power isolation internally via on-chip transformers, eliminating the drawbacks of traditional optocouplers such as ageing, bulkiness, and low data rates. It significantly simplifies the design of isolated I²C interfaces while delivering high performance and reliability.

Key features of the ADUM2250ARWZ include:

Bidirectional isolation: Integrates two complete bidirectional channels, perfectly supporting bidirectional data transmission for the I²C protocol.

High performance: Supports I²C clock frequencies up to 1 MHz, low propagation delay of 162 ns, and common-mode transient immunity (CMTI) up to 35 kV/μs, ensuring high-speed, reliable data transmission even in harsh electrical environments.

Wide supply range: Operates across a broad 3.0V to 5.5V supply voltage range, enabling seamless compatibility with both 3.3V and 5V systems.

High drive capability: Provides 30 mA sink current capability, enabling driving of heavier bus loads.

High reliability: Designed for operation over the -40°C to +105°C temperature range, suitable for demanding industrial and automotive environments.

Integrated hot-swap control: Built-in hot-swap circuitry supports power-up/power-down switching.

The ADUM2250ARWZ is ideally suited for the following applications:

Isolated I²C/SMBus/PMBus interfaces: Critical for isolating communication buses in power management systems (e.g., digital power, intelligent battery management).

Industrial automation and control systems: Programmable logic controllers (PLCs), industrial sensors, data acquisition modules, etc., for isolating MCUs from peripherals while suppressing ground noise and surges.

Communications infrastructure: Power and monitoring modules in network switches, routers, base stations, and similar equipment.

Power over Ethernet (PoE) systems: Isolating the interface between PoE controllers and powered devices.
