Product details
Overview
ADUM5202WCRWZ from Analog Devices is a dual-channel, automotive-qualified digital isolator with integrated isoPower® DC-to-DC converter delivering regulated 3.3 V or 5.0 V isolated output up to 400 mW, supporting 25 Mbps NRZ data rates and operating from −40°C to +105°C. It provides galvanic isolation for signal and power in high-noise automotive systems such as battery management and motor control interfaces.
For engineers reviewing the ADUM5202WCRWZ datasheet, ADUM5202WCRWZ pinout, ADUM5202WCRWZ application, or ADUM5202WCRWZ equivalent, this page delivers verified technical context, exact pin functions, automotive safety certifications (UL, VDE, CSA), real-world power delivery specs (e.g., 94 mA load current at 5 V→3.3 V conversion), and validated alternative options for functional replacement in ISO 26262-relevant designs.
Technical Context
The ADUM5202WCRWZ uses iCoupler® chip-scale transformers for both signal isolation and magnetic energy transfer in its integrated DC-to-DC converter, eliminating external isolated power supplies. Its dual-channel architecture supports independent input/output directionality per channel, with propagation delay skew ≤15 ns between units and pulse width distortion ≤6 ns.
It operates under three voltage configurations: 5 V→5 V (400 mW), 5 V→3.3 V (up to 94 mA), or 3.3 V→3.3 V (21 mA), all with 34% peak efficiency and <75 mVp-p output ripple. Safety compliance includes reinforced insulation (VIORM = 560 VPEAK) per IEC 60747-5-2 and UL 1577 2500 Vrms/1 min rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 25 Mbps NRZ - supports high-speed CAN FD, SPI, and UART isolation without external clocking. |
| Isolation Voltage | 2500 Vrms for 1 minute - meets automotive system-level surge immunity requirements per ISO 16750-2. |
| Output Power | Up to 400 mW at 5 V output - powers isolated gate drivers, ADCs, or sensors without secondary LDOs. |
| Common-Mode Immunity | >25 kV/µs - maintains signal integrity during fast transients in EV traction inverters or 48 V DC-DC converters. |
| Operating Temperature | −40°C to +105°C - qualified per AEC-Q100 Grade 2, suitable for under-hood and battery-pack environments. |
| Propagation Delay Skew | ≤15 ns - enables precise timing alignment across dual-channel feedback paths in motor phase control. |
| Regulated Output Options | Selectable 3.3 V or 5.0 V via VSEL pin - eliminates need for external regulators when interfacing with mixed-voltage MCUs. |
Pinout & Package
16-lead SOIC package with 7.6 mm creepage distance and reinforced insulation barrier; RoHS-compliant, automotive-grade molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Primary-side supply input | Accepts 3.0–5.5 V; powers primary logic and isoPower oscillator circuitry. |
| GND1 (Pins 2, 8) | Primary-side ground reference | Internally shorted; must connect both pins to low-impedance primary ground plane. |
| VIA / VIB | Primary-side logic inputs | Channel A and B inputs; CMOS-compatible thresholds (VIH = 0.7×VDD1). |
| VOA / VOB | Secondary-side logic outputs | Isolated outputs with VOH ≥ VISO − 0.5 V at 4 mA drive - directly interface 3.3 V or 5 V receivers. |
| VISO | Isolated DC output | Regulated 3.3 V or 5.0 V supply for secondary-side circuitry; max 94 mA at 5 V→3.3 V mode. |
| GNDISO (Pins 9, 15) | Secondary-side ground reference | Internally shorted; forms return path for isolated power and signals - must be separated from GND1. |
| VSEL | Output voltage selection | Connect to GNDISO for 3.3 V output; connect to VISO for 5.0 V output - sets isoPower regulation setpoint. |
| RCSEL | Regulation mode control | High = self-regulation; low = slave mode - enables daisy-chained multi-isolator power architectures. |
| VE2 | Secondary output enable | Active-high; drives VOA/VOB into high-Z when low - supports dynamic power gating in sleep modes. |
| RCIN | Regulation control input | Accepts RCOUT from master isolator or tied low; never tie high in slave mode - prevents overvoltage damage. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated isoPower DC-DC converter | Eliminates external isolated DC-DC modules - reduces BOM count and PCB area in space-constrained automotive ECUs. |
| Automotive qualification (AEC-Q100 Grade 2) | Validated for −40°C to +105°C operation with lifetime reliability testing - suitable for ASIL-B system components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel isolated power applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM5201WCRWZ | Input A → Output B, Input B → Output A pinout (crossed channel mapping); identical specs otherwise. | Suitable for designs requiring inverted channel routing to match existing PCB layout or legacy firmware I/O mapping. | Select when board layout requires swapped signal flow between primary and secondary sides without redesign. |
| SI8822ED-IS | Capacitive isolation; 5 V only output; lower max load (60 mA); no VSEL pin; different pinout and RCSEL logic. | Used where lower cost and smaller footprint are prioritized over flexible output voltage selection and automotive temperature range. | Choose for non-automotive industrial applications needing basic 2-channel isolation with simpler regulation scheme. |
Compared with ADUM5202WCRWZ, ADUM5201WCRWZ offers identical performance but reversed channel mapping - ideal for layout reuse - while SI8822ED-IS trades voltage flexibility and AEC-Q100 qualification for lower unit cost and capacitive-based reliability in less demanding environments.

FAQ
What is the maximum output current capability of the ADUM5202WCRWZ in 5 V input to 3.3 V output mode?
The ADUM5202WCRWZ delivers up to 94 mA of continuous output current when configured for 5 V primary input and 3.3 V isolated output, as specified in Table 11 of the datasheet. This value reflects actual load capability under thermal limits at TA = 25°C; derating applies above 70°C ambient per Figure 5's thermal derating curve. The ADUM5202WCRWZ maintains regulation within ±5% load regulation spec across this range.
Does the ADUM5202WCRWZ support AEC-Q100 qualification, and what grade is it rated for?
Yes, the ADUM5202WCRWZ is qualified per AEC-Q100 Grade 2, meaning it is rated for operation from −40°C to +105°C ambient temperature and has undergone stress testing including HTOL, TC, and UHAST. This qualification is explicitly stated in the "Automotive Products" header and General Description section of the Rev. 0 datasheet, confirming its suitability for under-hood and battery-pack applications.
How does the VSEL pin configure the isolated output voltage on the ADUM5202WCRWZ?
On the ADUM5202WCRWZ, the VSEL pin selects the isoPower output voltage: connecting VSEL to GNDISO configures VISO for 3.3 V regulation, while connecting VSEL to VISO configures it for 5.0 V regulation. This selection is active only in self-regulation mode (RCSEL = high); in slave mode, VSEL has no function. The ADUM5202WCRWZ's internal regulator adjusts switching duty cycle to maintain the selected setpoint across load and line variations.
Can the ADUM5202WCRWZ be used in a daisy-chained power architecture with other isoPower devices?
Yes, the ADUM5202WCRWZ supports daisy-chained power topologies via its RCIN and RCSEL pins. When RCSEL is low, the device operates in slave mode and accepts regulation control from the RCOUT pin of a master isoPower device (e.g., ADUM5200W). This allows multiple ADUM5202WCRWZ units to share a single master's regulation loop, simplifying system-level power management in multi-isolator designs.
What safety certifications does the ADUM5202WCRWZ hold, and what do they cover?
The ADUM5202WCRWZ holds UL 1577 (2500 Vrms/1 min), CSA Component Acceptance Notice #5A, and VDE IEC 60747-5-2 (VIORM = 560 VPEAK, reinforced insulation) certifications. These validate its dielectric strength, creepage/clearance distances (7.6 mm), and lifetime insulation performance under continuous working voltage - covering both functional safety and regulatory compliance for automotive and industrial end equipment.
