Product details
Overview
ADUM5403WCRWZ-1 from Analog Devices is a quad-channel digital isolator with integrated isoPower® dc-to-dc converter, delivering regulated 3.3 V isolated output up to 89 mA (5 V input / 3.3 V output mode), supporting 25 Mbps NRZ data rates, and qualified for automotive applications with 105°C operation and 7.6 mm creepage in 16-lead SOIC package. It enables compact battery management and motor control interfaces where galvanic isolation and local power are both required.
For engineers reviewing the ADUM5403WCRWZ-1 datasheet, ADUM5403WCRWZ-1 pinout, ADUM5403WCRWZ-1 application, or ADUM5403WCRWZ-1 equivalent, key selection criteria include its 25 Mbps channel speed, 3.3 V isolated supply capability under 5 V primary input, 25 kV/µs common-mode transient immunity, reinforced insulation rating (VIORM = 565 V peak), and automotive qualification per AEC-Q100.
Technical Context
The ADUM5403WCRWZ-1 implements iCoupler® chip-scale transformer technology for both signal isolation and magnetic power transfer, eliminating external isolated DC/DC converters. Its internal PWM-controlled oscillator operates at 625 kHz with 180 MHz switching frequency, enabling up to 500 mW total isolated power (derated to 297 mW at 3.3 V output under 5 V input).
It features codirectional channel matching of ≤6 ns skew and opposing-directional skew ≤15 ns, with propagation delay ≤60 ns and pulse width distortion ≤6 ns across all four channels. The device includes undervoltage lockout (2.4 V–2.7 V thresholds) on both VDD1 and VISO rails and supports dual-supply configurations (5 V/5 V, 5 V/3.3 V, or 3.3 V/3.3 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 25 Mbps NRZ - supports high-speed CAN FD, SPI, and RS-485 interface isolation without timing bottlenecks |

| Operating Temperature | −40°C to +105°C - validated for under-hood and battery-pack mounting locations |
| Package | 16-lead SOIC (wide-body, 7.6 mm creepage) - provides certified spacing for high-voltage automotive PCB layouts |
Pinout & Package
ADUM5403WCRWZ-1 uses a 16-lead SOIC_W package with creepage ≥7.6 mm, designed for reinforced insulation in automotive and industrial applications. Pin numbering follows standard SOIC convention (Pin 1 = top-left corner, counterclockwise).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Primary-side supply input | Accepts 3.0–5.5 V; powers input-side logic and isoPower oscillator |
| GND1 | Primary-side ground reference | Return path for VDD1 and input-side I/O; must be separated from GNDISO by isolation barrier |
| VIA, VIB, VIC, VID | Input data channels (A–D) | CMOS-compatible inputs referenced to VDD1/GND1; support 25 Mbps NRZ |
| VOA, VOB, VOC, VOD | Output data channels (A–D) | CMOS outputs referenced to VISO/GNDISO; drive loads up to ±10 mA |
| VISO | Isolated secondary supply output | Regulated 3.3 V (or 5.0 V) output; supplies isolated-side logic and outputs |
| GNDISO | Isolated-side ground reference | Return for VISO and output-side I/O; galvanically isolated from GND1 |
| VSEL | Output voltage select | Connected to GNDISO for 3.3 V VISO mode; connected to VISO for 5.0 V mode |
| RCOUT | Regulator control output | Internal feedback node for isoPower regulation; not intended for external loading |
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 |
|---|---|---|---|
| ADUM5403WARWZ-1 | Same pinout and specs, but rated for −40°C to +125°C ambient and qualified to AEC-Q100 Grade 1 | Suitable for under-hood applications exceeding 105°C case temperature (e.g., near inverter heat sinks) | Select when extended temperature margin or Grade 1 qualification is required; otherwise ADUM5403WCRWZ-1 suffices for most BMS modules. |
| SI88442ED-IS | Quad-channel isolator with integrated 5 V isolated supply (max 100 mA); no 3.3 V output option; uses capacitive isolation | Lacks native 3.3 V VISO mode - requires external LDO for 3.3 V loads; lower CMTI (15 kV/µs) | Consider only if 5 V isolated supply is acceptable and cost sensitivity outweighs CMTI and automotive qualification requirements. |
Compared with ADUM5403WCRWZ-1, ADUM5403WARWZ-1 extends thermal operating range for extreme under-hood placement, while SI88442ED-IS trades automotive qualification and CMTI for lower unit cost and higher isolated current - but requires additional regulation for 3.3 V loads and lacks reinforced insulation certification for ASIL-B.

FAQ
What is the maximum isolated output current supported by ADUM5403WCRWZ-1 in 5 V input / 3.3 V output configuration?
ADUM5403WCRWZ-1 delivers up to 89 mA of regulated 3.3 V isolated output current when supplied with 5 V on VDD1 (per Table 11). This value is derated at elevated temperatures: at 105°C ambient, maximum continuous VISO load is 60 mA (per Absolute Maximum Ratings table). The device includes thermal protection and UVLO to safeguard against overload conditions.
Does ADUM5403WCRWZ-1 support 3.3 V primary-side operation?
Yes, ADUM5403WCRWZ-1 supports 3.3 V primary-side operation with 3.3 V isolated output (VSEL = GNDISO), delivering up to 49 mA (Table 7). Input voltage range is 3.0 V to 5.5 V, and the device maintains 25 Mbps data rate and full specification compliance across both 3.3 V and 5 V VDD1 modes.
How does the W-1 suffix in ADUM5403WCRWZ-1 affect startup behavior?
The W-1 suffix denotes an upgraded internal voltage reference that ensures reliable VISO startup under all load conditions - including heavy initial loads and low-temperature environments. This enhancement prevents brownout-induced reset loops during cold cranking in automotive battery systems, a known limitation of earlier non-W-1 variants.
What safety certifications apply to ADUM5403WCRWZ-1?
ADUM5403WCRWZ-1 holds UL 1577 (2500 Vrms, 1 min), CSA Component Acceptance Notice 5A, and VDE EN 60747-5-2 (VIORM = 565 Vpeak, reinforced insulation). The package bears the * marking confirming VDE 0884-2 approval. These certifications validate its use in ASIL-B functional safety paths per ISO 26262.
Can ADUM5403WCRWZ-1 replace ADUM5403CRWZ-1 in existing designs?
Yes, ADUM5403WCRWZ-1 is a direct drop-in replacement for ADUM5403CRWZ-1, sharing identical pinout, electrical specifications, and package. The "W" prefix indicates automotive qualification (AEC-Q100), and "-1" denotes the enhanced voltage reference - both improvements that do not affect compatibility. No PCB or firmware changes are required.
What is the role of the RCOUT pin on ADUM5403WCRWZ-1?
RCOUT is an internal regulator control output used for feedback within the isoPower dc-to-dc converter. It is not intended for connection to external loads or measurement circuits. Driving or loading RCOUT may disrupt regulation stability and is explicitly discouraged in the datasheet; it should remain unconnected in standard applications.
