Product details
Overview
ADuM5403WCRWZ from Analog Devices is a quad-channel digital isolator with integrated isoPower® dc-to-dc converter, delivering up to 500 mW isolated output power at 5 V or 330 mW at 3.3 V, supporting 25 Mbps NRZ data rates, and qualified for automotive applications. It provides reinforced isolation (VIORM = 565 V peak) in a 16-lead SOIC package with 7.6 mm creepage, operating from −40°C to +105°C.
For engineers reviewing the ADuM5403WCRWZ datasheet, ADuM5403WCRWZ pinout, ADuM5403WCRWZ application, or ADuM5403WCRWZ equivalent, key selection criteria include regulated isolated supply capability, channel direction configuration (VOA/VOB/VOC/VID output mapping), common-mode transient immunity (>25 kV/μs), and compliance with UL 1577, VDE 0884-2, and CSA Component Acceptance Notice #5A.
Technical Context
The ADuM5403WCRWZ 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 (625 kHz) and high-frequency switching (180 MHz) enable compact, fully integrated isolation with four independent unidirectional channels.
Unlike ADuM5401W and ADuM5402W, the ADuM5403WCRWZ features a specific pinout where VOA and VOB are on the input side (pins 3 and 4), while VOC and VID are on the output side (pins 13 and 11), enabling asymmetric bidirectional system partitioning. It includes undervoltage lockout (2.4 V–2.7 V thresholds) and supports three input/output voltage combinations: 5 V/5 V, 5 V/3.3 V, and 3.3 V/3.3 V.

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 |
|---|---|---|---|
| ADuM5402WCRWZ | Identical package and isolation specs, but VOA/VOB/VOC/VOD pinout places all outputs on output side (pins 11–14); no input-side outputs | Suitable when all four isolated signals drive downstream devices only - not for bidirectional feedback paths requiring input-side outputs | Select ADuM5402WCRWZ if system architecture requires all four channels to be output-only toward isolated peripherals. |
| SI88642ED-IS | Quad-channel isolator with integrated DC/DC (3.3 V/5 V), but uses capacitive isolation and offers 375 mW max output; no AEC-Q100 qualification | Lacks automotive qualification and has lower CMTI (15 kV/μs); suited for industrial PLCs, not EV battery domains | Choose SI88642ED-IS only for cost-sensitive non-automotive applications where AEC-Q100 and >25 kV/μs CMTI are not required. |
Compared with ADuM5402WCRWZ and SI88642ED-IS, the ADuM5403WCRWZ uniquely supports mixed-direction signal routing (outputs on both sides) and delivers highest isolated power (500 mW) with automotive-grade reliability - making it optimal for BMS and inverter control where bidirectional monitoring and local power generation are essential.

FAQ
What is the maximum isolated output current supported by the ADuM5403WCRWZ?
The ADuM5403WCRWZ supports up to 100 mA output current at 5 V (500 mW) when VDD1 = 5 V and TA ≤ 85°C. At 105°C ambient, the maximum allowable VISO load current reduces to 60 mA per Absolute Maximum Ratings Table 19. This derating ensures safe thermal operation in automotive battery enclosures where ambient temperature exceeds 85°C.
How does the ADuM5403WCRWZ differ from the ADuM5401WCRWZ in pin configuration?
The ADuM5403WCRWZ assigns VOA and VOB to pins 3 and 4 (input-side outputs), while ADuM5401WCRWZ places all four outputs (VOA–VOD) on the output side (pins 11–14). This makes ADuM5403WCRWZ ideal for architectures requiring feedback signals to originate from the isolated side and terminate on the MCU side without additional level-shifting components.
Can the ADuM5403WCRWZ be used with a 3.3 V primary supply?
Yes, the ADuM5403WCRWZ supports 3.3 V primary operation (VDD1 = 3.3 V) with VSEL tied to GNDISO, delivering regulated 3.3 V at VISO with up to 60 mA output current. Electrical Characteristics Table 6 confirms 3.0–3.6 V VISO setpoint and 33% efficiency at full load, making it suitable for low-voltage microcontroller domains.
What safety certifications apply to the ADuM5403WCRWZ?
The ADuM5403WCRWZ holds UL 1577 recognition (2500 V rms, 1 min), CSA Component Acceptance Notice #5A, and VDE certification per DIN EN 69747-5-2 (VDE 0884-2):2003-1 with VIORM = 565 V peak. The "*" marking on the package denotes VDE compliance, and all units undergo 100% production partial discharge testing at 1059 V peak.
Does the ADuM5403WCRWZ require external filtering components for the isolated DC/DC output?
Yes, the ADuM5403WCRWZ requires a 0.1 µF ceramic capacitor in parallel with a 10 µF bulk capacitor (CBO) at the VISO pin to meet ripple specifications (≤75 mV p-p at 5 V/90 mA). Per Figure 21 in AN-0971, improper capacitor placement or ESR mismatch causes excessive noise and can trigger UVLO on the isolated rail.
