Product details
Overview
ADUM5402WCRWZ-1 from Analog Devices is a quad-channel digital isolator with integrated isoPower® dc-to-dc converter, delivering regulated 5 V or 3.3 V isolated output up to 500 mW. It provides 25 Mbps NRZ signal isolation across four channels, features 7.6 mm creepage in a 16-lead SOIC package, and operates from −40°C to +105°C for automotive battery management systems.
For engineers reviewing the ADUM5402WCRWZ-1 datasheet, ADUM5402WCRWZ-1 pinout, ADUM5402WCRWZ-1 application, or ADUM5402WCRWZ-1 equivalent, this page delivers verified specifications, functional pin mapping, safety-certified isolation parameters, and automotive-grade thermal and regulatory compliance data required for high-reliability isolated power and signal transfer design.
Technical Context
The ADUM5402WCRWZ-1 uses iCoupler® chip-scale transformer technology for both logic signal isolation and magnetic power transfer, eliminating external isolated DC/DC converters. Its integrated converter operates at 625 kHz PWM frequency with 180 MHz oscillator frequency, supporting 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).
It implements dual-supply undervoltage lockout (UVLO) with 2.7 V rising and 2.4 V falling thresholds on both VDD1 and VISO rails, and achieves >25 kV/µs common-mode transient immunity via differential transformer coupling. Channel matching is specified at ≤6 ns codirectional skew and ≤15 ns opposing-directional skew under full temperature range.
Key Specifications

|---|---|
| Data Rate | 25 Mbps NRZ - supports high-speed CAN, SPI, and digital I/O isolation without external retiming. |
| Isolation Voltage | 2500 V rms (1 min UL 1577) - certified reinforced insulation for functional safety in automotive 400 V battery systems. |
| Output Power | Up to 500 mW @ 5 V - sufficient to power downstream isolated MCU peripherals, ADCs, or gate drivers without auxiliary supply. |
| Propagation Delay | 45–60 ns - enables precise timing-critical applications like motor control feedback loops and real-time sensor interfaces. |
| Common-Mode Immunity | >25 kV/µs - maintains signal integrity during fast transients in EV battery pack switching noise environments. |

| Package | 16-lead SOIC wide-body (RWZ) - 7.6 mm creepage meets DIN EN 69747-5-2 reinforced insulation requirements. |
Pinout & Package
ADUM5402WCRWZ-1 is housed in a 16-lead SOIC wide-body (RWZ) package with creepage ≥7.6 mm and reinforced insulation rated to 565 VPEAK. Pin functions are defined per Figure 3 of the ADuM5401W/ADuM5402W/ADuM5403W Rev. F datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (VIA, VIB, VIC, 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 (VOA, VOB, VOC, VOD) | Secondary-side digital outputs | Drive CMOS loads referenced to VISO/GNDISO; VOH ≥ VISO − 0.5 V @ 4 mA sink. |
| 9, 10 (GNDISO, VISO) | Isolated output power terminals | VISO supplies regulated 3.3 V or 5 V to secondary-side circuitry; GNDISO is isolated return path. |
| 11, 12 (GND1, VDD1) | Primary-side power terminals | VDD1 accepts 3.0–5.5 V input; GND1 is primary reference; UVLO triggers below 2.4 V. |
| 13 (VSEL) | Output voltage select | GNDISO = 3.3 V output; VDD1 = 5 V output; internal reference upgrade ensures reliable startup under all loads. |
| 14 (RCOUT) | Regulator control output | Nonstandard interface for cascading isoPower devices; not intended for general-purpose digital loads. |
| 15, 16 (NC) | No-connect | Internally unused; must remain unconnected per datasheet layout guidance. |

FAQ
What is the maximum isolated output power of the ADUM5402WCRWZ-1?
The ADUM5402WCRWZ-1 delivers up to 500 mW of regulated isolated output power when configured for 5 V input and 5 V output. At 5 V input / 3.3 V output, it supplies up to 330 mW; at 3.3 V input / 3.3 V output, it supplies up to 200 mW. These values are confirmed in Table 1 of the Rev. F datasheet and reflect actual load capability under specified thermal conditions.
Does the ADUM5402WCRWZ-1 require external filtering components for its DC/DC converter?
Yes, the ADUM5402WCRWZ-1 requires external capacitors on the VISO rail: a 0.1 µF ceramic capacitor in parallel with a 10 µF bulk capacitor (CBO) is mandatory per datasheet Section "Electrical Characteristics" and AN-0971. These components suppress output ripple (<75 mV p-p at 90 mA load) and ensure stable regulation under dynamic load conditions.
How does the VSEL pin configure the ADUM5402WCRWZ-1 output voltage?
The VSEL pin selects the isolated output voltage: tying VSEL to GNDISO configures the ADUM5402WCRWZ-1 for 3.3 V output; tying VSEL to VDD1 configures it for 5.0 V output. This selection determines the internal regulator setpoint and is validated across all operating temperatures and load ranges per Tables 2, 6, and 10 in the datasheet.
Is the ADUM5402WCRWZ-1 pin-compatible with non-W variants like ADUM5402ARWZ?
Yes, the ADUM5402WCRWZ-1 shares identical pinout, footprint, and electrical interface with ADUM5402ARWZ and ADUM5402BRWZ. The W-suffix denotes AEC-Q100 qualification and an upgraded internal voltage reference for improved startup behavior - no PCB layout changes are needed for drop-in replacement in existing designs meeting automotive qualification requirements.
What safety certifications apply to the ADUM5402WCRWZ-1?
The ADUM5402WCRWZ-1 holds UL 1577 recognition (2500 V rms, 1 min), CSA Component Acceptance Notice 5A, VDE certification per DIN EN 69747-5-2 (VIORM = 565 V peak), and CQC certification per GB4943.1-2011. All certifications are production-tested and marked with the * symbol on the package per datasheet Table 15 and Section "Regulatory Approvals".
