Overview

The ADuM5401WCRWZ-1RL is a quad-channel digital isolator featuring integrated isoPower, an isolated DC-to-DC converter that provides up to 500mW of regulated power. It utilizes Analog Devices' iCoupler technology to provide 2500Vrms isolation and 25Mbps data rates without the need for a separate isolated power supply. This automotive-qualified component is designed to eliminate the complexity of isolated power circuitry in space-constrained designs.

Why Choose This Part

The primary advantage is the integration of an isolated DC-to-DC converter, which saves significant PCB area and reduces the bill of materials by eliminating external transformers. It supports a wide supply range of 3V to 5.5V and offers high common-mode transient immunity of 25kV/us, ensuring reliable data transmission in noisy industrial or automotive environments.

Applications

RS-232/RS-422/RS-485 Transceivers
Provides both signal isolation and the necessary isolated power for bus transceivers in industrial networks.
Automotive Battery Management Systems
Safe monitoring of high-voltage battery stacks while providing isolated communication to the main ECU.
Industrial Fieldbus Isolation
Used in CAN bus or generic digital interfaces to prevent ground loops and protect sensitive logic from high-voltage transients.
Isolated Sensor Interfaces
Powers and isolates remote ADC or sensor front-ends in harsh EMI environments.

Getting Started

To evaluate this part, use the EVAL-ADuM5401EBZ evaluation board which provides footprints for peripheral components and SMA or header connections for signal integrity testing. Ensure that the layout follows strict electromagnetic interference (EMI) guidelines, specifically regarding the stitching capacitance and ferrite bead placement on the VISO and GNDISO pins to meet CISPR 22 Class B standards.
