ADUM5200CRWZ Обзор
A digital isolator is a semiconductor device that transfers logic signals across a galvanic isolation barrier (typically using transformer, capacitive, or optical coupling) while blocking DC and high-voltage transients. Isolators are categorized by isolation voltage (1.5 kV, 2.5 kV, 5 kV rms), channel count (1-8), and data rate (DC to >100 Mbps). The ADUM5200 belongs to the isoPower family, a sub-category that integrates a regulated isolated supply alongside the data channels, eliminating the need for a separate isolated DC/DC module. In the broader system hierarchy, digital isolators sit between logic-level signals and high-voltage domains in industrial, medical, and energy systems.
Key specifications include 2.5 kV rms isolation voltage, 25 Mbps data rate per channel (NRZ signaling), 25 kV/us minimum common-mode transient immunity (CMTI), 3.3 V or 5 V regulated output, and up to 500 mW output power from a 5.0 V input. The Schmitt-trigger inputs ease interfacing with slow or noisy sources, and the wide-body SOIC package provides >8 mm creepage per IEC 60601 / IEC 60747-17 spacing requirements for reinforced isolation.
The device uses a planar transformer-based DC/DC converter stage with PWM control. Internal regulation feedback is sent across the isolation barrier via a proprietary iCoupler channel, allowing tight output regulation without optocouplers. The result is a smaller BOM and a simpler PCB layout versus discrete solutions, at the cost of lower maximum output power than dedicated isolated converter modules.
Typical applications include isolated RS-232/RS-485 interfaces, isolated gate-drive power for IGBT/MOSFET bridges, industrial fieldbus (Profibus, CAN) isolation, medical device patient-isolated interfaces, and renewable-energy inverter control. The high CMTI rating makes the part especially suitable for driving power-converter gate drivers across noisy high-voltage domains.
When designing with the ADUM5200CRWZ, observe the decoupling recommendations in the datasheet (10 uF low-ESR on VDD and VISO) and respect the thermal envelope: at 500 mW output and 85% efficiency the part dissipates roughly 0.5 W internally. Provide adequate copper area beneath the exposed paddle region to keep junction temperature within the 105 C maximum.

Типичное применение
ADUM5200CRWZ подходит для 7 применениеs: Isolated RS-485 / RS-422 Interface, IGBT / MOSFET Gate Driver Power Supply, Industrial Fieldbus Isolation (CAN / Profibus / DeviceNet), Medical Patient-Isolated Data Interface, Solar Inverter Control and Monitoring, Isolated SPI / UART Bridge for Microcontroller, Automotive ECU Isolated Communication.
Isolated RS-485 / RS-422 Interface
The ADUM5200CRWZ is well-suited for isolated RS-485/RS-422 nodes because it provides both signal isolation and an integrated 5 V (or 3.3 V) isolated supply rail that can power an isolated transceiver. With 2.5 kV rms isolation and 25 kV/us CMTI, the part tolerates the high dV/dt noise present on long industrial bus cables and motor-drive cabinets. The 25 Mbps data rate supports RS-485 at full 40 Mbps and oversampling for high-speed CAN-FD bridges.
Рекомендуется
IGBT / MOSFET Gate Driver Power Supply
In motor-drive and inverter designs, the ADUM5200CRWZ delivers an isolated 5 V rail for the primary side of gate-driver ICs while carrying PWM control signals across the 2.5 kV barrier. Its 25 kV/us CMTI rating is essential for surviving the fast dV/dt events produced by switching 600 V-1200 V IGBT or SiC MOSFET bridges. The 500 mW output budget covers a single high-side/low-side gate driver pair, eliminating a discrete isolated DC/DC module.
Рекомендуется
Industrial Fieldbus Isolation (CAN / Profibus / DeviceNet)
The ADUM5200CRWZ is used to isolate 24 V industrial fieldbus nodes including CAN, Profibus DP, and DeviceNet. Its 2.5 kV rms rating and 7.6 mm creepage meet the reinforced isolation requirements of IEC 61131-2 for PLC digital inputs. Two independent 25 Mbps channels allow simultaneous isolation of the bus data line and a control/enable signal, while the 500 mW isoPower output can power the isolated transceiver plus basic protection circuitry.
Рекомендуется
Medical Patient-Isolated Data Interface
Patient-connected medical devices require 2.5 kV of galvanic isolation per IEC 60601-1 between the patient side and the operator/host side. The ADUM5200CRWZ delivers 2.5 kV rms isolation with 7.6 mm creepage, and its integrated isoPower stage provides a 5 V or 3.3 V rail for the patient-isolated sensor front-end. The wide-body 16-SOIC package supports the required PCB spacing for patient-isolation creepage/clearance budgets.
Рекомендуется
Solar Inverter Control and Monitoring
In photovoltaic inverter and energy-storage designs, the ADUM5200CRWZ isolates the low-voltage MCU side from the high-voltage DC bus while powering isolated gate drivers or current-sense amplifiers. The 25 kV/us CMTI is critical for surviving the hard-switching transients of IGBT half-bridges at 600 V-1200 V. Two channels allow simultaneous isolation of PWM command and a fault/feedback signal in the same 16-SOIC footprint.
Рекомендуется
Isolated SPI / UART Bridge for Microcontroller
The ADUM5200CRWZ is commonly deployed as an SPI-to-isolated-SPI bridge for 4-wire SPI buses crossing a safety barrier. With 45 ns typical propagation delay and 25 Mbps throughput, it cleanly supports SPI clock rates up to approximately 10 MHz, sufficient for sensor readout and display-driving MCUs. The integrated 500 mW isoPower supply is large enough to power the isolated MCU node plus a small sensor or display driver.
Рекомендуется
Automotive ECU Isolated Communication
For automotive ECU designs requiring isolation (battery management systems, traction inverter control), the ADUM5200WCRWZ (AEC-Q100 variant) is the preferred drop-in selection. It retains the same 16-SOIC wide-body footprint and 2.5 kV isolation while adding the automotive temperature grade (-40 C to +125 C). The integrated isoPower rail powers CAN transceivers or local MCU regulators across the high-voltage traction domain.

Заметки по проектированию
Place a low-ESR 10 uF ceramic decoupling capacitor (X5R or X7R, 10 V minimum) on both VDD1 and VISO rails, located within 2 mm of the respective pins. The ADUM5200CRWZ datasheet mandates these capacitors for stable isoPower regulation. Add a 0.1 uF high-frequency bypass cap in parallel for switching noise suppression. Without proper decoupling, output ripple will exceed datasheet limits and may cause logic errors on the isolated side.
Estimated: at 500 mW isolated output and 85% isoPower efficiency, the device dissipates roughly 88 mW internally (500 mW output / 0.85 - 500 mW output). With 16-SOIC wide-body thermal resistance theta_JA of approximately 80 C/W on a standard 4-layer JEDEC test board, the junction temperature rise is around 7 C - well within the 105 C maximum. For high-temperature environments, provide additional copper area beneath the paddle region on the primary side.
Maintain the 7.6 mm creepage and clearance required by IEC 60747-17 by routing all primary-side traces inside the package outline on one PCB layer, and all isolated-side traces on inner or opposite layers. Avoid placing any copper (traces, vias, or polygons) under the package between the primary and isolated sides - this would compromise creepage and reduce effective isolation voltage.
Do not connect bypass capacitors across the isolation barrier - this couples switching noise directly into the logic signals. Ensure the VDD1 supply is clean: ripple above 50 mVpk can pass through the internal PWM modulator and couple into the isoPower output. For applications requiring <100 mVpk ripple on VISO, add an external LC filter (10 uH inductor + 10 uF capacitor) per the datasheet application notes.
