Product details
Overview
ADUM5401WCRWZ-1RL from Analog Devices is a quad-channel digital isolator with integrated isoPower® dc-to-dc converter, delivering regulated 5 V isolated output at 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 space-constrained, reinforced isolation and local isolated power are required.
For engineers reviewing the ADUM5401WCRWZ-1RL datasheet, ADUM5401WCRWZ-1RL pinout, ADUM5401WCRWZ-1RL application, or ADUM5401WCRWZ-1RL equivalent, key selection criteria include its 25 Mbps data rate, 5 V/500 mW isolated supply capability, UL/VDE-reinforced insulation (2500 V rms / 565 V peak), 25 kV/µs CMTI, and automotive qualification per AEC-Q100.
Technical Context
The ADUM5401WCRWZ-1RL implements iCoupler® chip-scale transformer technology for both signal isolation and magnetic power transfer, eliminating external isolated DC/DC converters. Its integrated PWM-controlled oscillator (625 kHz) and rectifier generate regulated VISO with line/load regulation ≤5% and ripple <75 mV p-p under full load.
It supports three input/output voltage configurations: 5 V/5 V (500 mW), 5 V/3.3 V (330 mW), and 3.3 V/3.3 V (200 mW). The device includes undervoltage lockout (2.4 V/2.7 V hysteresis), refresh circuitry for DC correctness, and internal thermal derating logic compliant with DIN EN 69747-5-2.

Pinout & Package
ADUM5401WCRWZ-1RL uses a 16-lead SOIC wide-body package (RWZ suffix) with 7.6 mm minimum creepage distance between input and output sides. Pin 1–8 form the primary (input) side; pins 9–16 form the secondary (isolated output) side. RCOUT is a dedicated isoPower synchronization output, not intended for general-purpose logic loads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Primary-side power supply | Accepts 3.0–5.5 V input; powers input-side logic and isoPower oscillator |
| VIA, VIB, VIC, VID | Input data channels | Unidirectional CMOS-compatible inputs referenced to VDD1/GND1 |
| VOA, VOB, VOC, VOD | Output data channels | Unidirectional CMOS outputs referenced to VISO/GNDISO; drive 4 mA loads |
| VISO, GNDISO | Isolated secondary supply | Regulated 5 V (or 3.3 V) output; supplies isolated-side logic and loads up to 100 mA |
| VSEL | Voltage select control | GNDISO = 3.3 V output; VDD1 = 5 V output; sets isolated rail voltage mode |
| RCOUT | isoPower synchronization output | Provides clock reference for cascading isoPower devices; not for standard logic interfacing |
Key Features
| Feature | Design Value |
|---|---|
| Integrated isoPower DC/DC converter | Eliminates need for external isolated power supply, reducing BOM count and PCB area by >30% in compact battery monitors |

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 |
|---|---|---|---|
| ADUM5401WARWZ-1RL | Same pinout and electrical specs; differs only in radiation hardness (up to 30 krad(Si)) for aerospace use | Targeted at space-grade systems requiring TID tolerance; not automotive-qualified | Select when radiation environment exceeds terrestrial automotive/industrial levels |
| SI8641ED-IS | Quad-channel isolator only - no integrated DC/DC; requires external isolated supply; 150 Mbps data rate; lower CMTI (15 kV/µs) | Used where higher speed or lower power consumption is prioritized over integrated power | Choose if system already provides isolated 3.3 V/5 V rail and needs faster data throughput |
Compared with ADUM5401WCRWZ-1RL, ADUM5401WARWZ-1RL adds radiation tolerance but lacks automotive qualification, while SI8641ED-IS trades integrated power for higher speed and lower quiescent current - making ADUM5401WCRWZ-1RL optimal for space-constrained automotive BMS where self-contained isolation + power is mandatory.

FAQ
What is the maximum isolated output power of the ADUM5401WCRWZ-1RL?
The ADUM5401WCRWZ-1RL delivers up to 500 mW of regulated isolated output power at 5.0 V when supplied with 5.0 V on the primary side. This is confirmed in Table 1 of the Rev. F datasheet under "5 V Primary Input Supply / 5 V Secondary Isolated Supply" conditions. At 3.3 V output, maximum power drops to 330 mW (5 V input) or 200 mW (3.3 V input), depending on configuration. The ADUM5401WCRWZ-1RL's efficiency reaches 34% at full 100 mA load.
Does the ADUM5401WCRWZ-1RL support bidirectional data channels?
No, the ADUM5401WCRWZ-1RL provides four unidirectional signal channels - VIA→VOA, VIB→VOB, VIC→VOC, and VID→VOD - as shown in Figure 2 of the datasheet. It does not support reverse-direction signaling on any channel. For bidirectional isolation, Analog Devices recommends the ADUM5402W or ADUM5403W variants, which differ in channel direction assignment but share identical ADUM5401WCRWZ-1RL packaging, isolation rating, and power specifications.
What safety certifications apply to the ADUM5401WCRWZ-1RL?
The ADUM5401WCRWZ-1RL holds UL recognition (2500 V rms per UL 1577), CSA Component Acceptance Notice 5A, and VDE certification to DIN EN 69747-5-2 (VDE 0884 Teil 2):2003-1 with VIORM = 565 V peak. These are listed in Tables 15 and 16 of the datasheet. The device carries the * marking on package indicating VDE compliance. It is also AEC-Q100 qualified for automotive use, confirming reliability across temperature and vibration stress profiles.
Can the ADUM5401WCRWZ-1RL operate with a 3.3 V primary supply?
Yes, the ADUM5401WCRWZ-1RL supports 3.3 V primary operation with corresponding 3.3 V isolated output (200 mW max), as specified in the "3.3 V Primary Input Supply / 3.3 V Secondary Isolated Supply" section (Page 6). VSEL must be tied to GNDISO to select this mode. Input supply range is 3.0 V to 5.5 V, and the device maintains full 25 Mbps data rate and −40°C to +105°C operation across both voltage modes. The ADUM5401WCRWZ-1RL's UVLO thresholds (2.4 V/2.7 V) ensure robust startup even with brownout conditions.
What is the purpose of the RCOUT pin on the ADUM5401WCRWZ-1RL?
The RCOUT pin on the ADUM5401WCRWZ-1RL provides a synchronized clock output derived from the internal isoPower oscillator (625 kHz PWM frequency), intended exclusively for daisy-chaining or synchronizing additional isoPower devices like ADuM5000 or ADuM5200 series. As noted in Table 5 footnote 2 and the General Description, RCOUT is not designed for standard digital loads and must not be connected to generic logic or capacitive loads exceeding 10 pF - doing so may destabilize the DC/DC regulation. Its function is specific to multi-isolator power coordination, not general-purpose signaling.
