Product details
Overview
ADuM5401WCRWZ-1 from Analog Devices is a quad-channel digital isolator with integrated isoPower® dc-to-dc converter, delivering regulated 5 V isolated output up to 500 mW. It provides four unidirectional signal isolation channels (25 Mbps NRZ), operates from −40°C to +105°C, and features 7.6 mm creepage in a 16-lead SOIC package - used in automotive battery management systems where galvanic separation and local isolated power are required.
For engineers reviewing the ADuM5401WCRWZ-1 datasheet, ADuM5401WCRWZ-1 pinout, ADuM5401WCRWZ-1 application, or ADuM5401WCRWZ-1 equivalent, key selection criteria include its reinforced insulation rating (VIORM = 565 V peak), high common-mode transient immunity (>25 kV/µs), automotive qualification, and integrated 5 V/500 mW isolated supply eliminating external DC/DC converters.
Technical Context
The ADuM5401WCRWZ-1 implements iCoupler® chip-scale transformer technology for both signal isolation and magnetic power transfer, enabling full galvanic separation between input and output sides. Its isoPower® architecture uses high-frequency PWM (625 kHz) switching with on-chip oscillator and rectifier to generate regulated VISO from VDD1.
It supports three operating configurations: 5 V input → 5 V isolated output (500 mW), 5 V input → 3.3 V isolated output (330 mW), and 3.3 V input → 3.3 V isolated output (200 mW). The W-1 variant includes an upgraded voltage reference ensuring reliable startup under all load conditions, distinguishing it from standard ADuM5401W versions.

Pinout & Package
ADuM5401WCRWZ-1 uses a 16-lead SOIC wide-body package (RWZ suffix) with 7.6 mm creepage distance, rated for reinforced insulation per DIN EN 69747-5-2 and UL 1577. Pin 1 is marked with dot; inputs (VIA–VID) reside on side 1 (pins 1–8), outputs (VOA–VOD, VISO, GNDISO) on side 2 (pins 9–16).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (VIA–VID) | Primary-side digital inputs | Accept CMOS-level signals referenced to VDD1/GND1; VIH ≥ 0.7×VDD1, VIL ≤ 0.3×VDD1 |
| 5, 6, 7, 8 (GND1, VDD1, VSEL, RCOUT) | Input-side power & control | VDD1 powers input logic; VSEL selects 3.3 V or 5 V VISO output; RCOUT is internal oscillator feedback (not for external loads) |
| 9, 10, 11, 12 (VOA–VOD) | Secondary-side digital outputs | Drive CMOS loads referenced to VISO/GNDISO; VOH ≥ VISO − 0.3 V, VOL ≤ 0.4 V @ 4 mA |
| 13, 14, 15, 16 (GNDISO, VISO, NC, NC) | Isolated power terminals | VISO delivers regulated isolated supply; GNDISO is dedicated return; pins 15–16 are no-connect |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel isolated power applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM5401ARWZ | No automotive qualification; lower CMTI (15 kV/µs); 500 mW output only at 5 V→5 V; no W-1 startup enhancement | Targeted at commercial-grade industrial automation, not automotive BMS | Select when AEC-Q100 compliance and guaranteed cold-start behavior are not required |
| SI8641ED-B-IS | External isolated DC/DC required; 4-channel signal-only isolation; no integrated power; higher max data rate (150 Mbps) | Suitable for high-speed protocols where local isolated power is provided separately | Choose when system already includes isolated supply and demands >25 Mbps throughput |
Compared with ADUM5401WCRWZ-1, ADUM5401ARWZ lacks automotive qualification and robust startup under heavy load, while SI8641ED-B-IS requires external power conversion but offers higher bandwidth - making ADUM5401WCRWZ-1 optimal for space-constrained, safety-certified automotive isolation with self-contained power.

FAQ
What is the maximum isolated output power of the ADuM5401WCRWZ-1?
The ADuM5401WCRWZ-1 delivers up to 500 mW of regulated isolated output power at 5 V when supplied with 5 V on the primary side. At 3.3 V input, it provides 200 mW at 3.3 V output; with 5 V input and 3.3 V output, it supplies 330 mW. These values are confirmed in Table 1 of the Rev. F datasheet and reflect actual load capability under recommended operating conditions.
Does the ADuM5401WCRWZ-1 support bidirectional data transmission?
No, the ADuM5401WCRWZ-1 provides four unidirectional isolation channels: VIA→VOA, VIB→VOB, VIC→VOC, and VID→VOD. Directionality is fixed per channel; for bidirectional communication, external logic or a different isolator (e.g., ADuM5402W) is required. This is explicitly defined in the functional block diagram and truth table of the ADuM5401W/ADuM5402W/ADuM5403W datasheet.
What safety certifications does the ADuM5401WCRWZ-1 hold?
The ADuM5401WCRWZ-1 is UL 1577 recognized (2500 V rms, 1 minute), CSA Component Acceptance Notice 5A approved, and VDE-certified to DIN EN 69747-5-2 (VDE 0884-2):2003-1 with VIORM = 565 V peak. It also carries CQC certification per GB4943.1-2011. All approvals apply to the RWZ package and are documented in Tables 15 and 16 of the Rev. F datasheet.
Can the ADuM5401WCRWZ-1 operate with a 3.3 V primary supply?
Yes, the ADuM5401WCRWZ-1 supports 3.3 V primary operation (VDD1 = 3.0 V to 3.6 V) with corresponding 3.3 V isolated output (VISO), delivering up to 200 mW. In this mode, typical input current is 44 mA with no VISO load and 175 mA at full VISO load. These specifications are detailed in Tables 6–7 (3.3 V primary/3.3 V secondary) of the Rev. F datasheet.
What is the purpose of the RCOUT pin on the ADuM5401WCRWZ-1?
The RCOUT pin on the ADuM5401WCRWZ-1 is an internal oscillator feedback node used exclusively for synchronization with other isoPower® devices (e.g., ADuM5000). It is not intended for connection to standard digital loads or external circuitry. The datasheet explicitly warns against using RCOUT for general-purpose signaling due to its nonstandard voltage levels and drive characteristics.
